    MEMORANDUM OPINION FOR TH E DEPUTY ATTORNEY
    G EN ER A L AN D T H E ASSOCIATE ATTORNEY G E N E R A L
    This responds to your joint request for our views regarding the
    authority of the President to expel foreign diplomatic personnel from
    the United States, to maintain control over the premises of Iranian
    diplomatic property in connection with that expulsion, and the legal
    constraints placed on that authority by international and domestic law
    and by our Constitution. For the reasons stated hereafter, we believe
    that the President has the authority to declare a nonresident alien who
    is a member of the staff of a foreign diplomatic or consular post in the
    United States to be persona non grata, forcibly to expel such diplomatic
    207
    personnel from the United States within a reasonable period of time (as
    set by the President) after being declared persona non grata, and to take
    all steps reasonably designed to secure all Iranian diplomatic properties
    and limit their use to diplomatic activities conducted by a third nation
    acceptable to the President. We conclude that the exercise of this
    power over diplomatic personnel is not constrained by the Immigration
    and Nationality Act of 1952, and that the Constitution requires only
    that a procedure reasonably calculated to insure that personnel actually
    expelled are those previously declared persona non grata be utilized.
    We also conclude that prior to their expulsion, diplomatic personnel
    are not entitled as a' matter of law to assert any federal statutory right
    to remain in this country as a means of avoiding their expulsion.1
    Finally, we believe that judicial review of any actions taken by the
    President related to expulsion would be limited to possible inquiry by
    habeas corpus into the question whether a particular person to be
    expelled was in fact previously declared persona non g rata.2
    I. Presidential Authority Over Diplomatic Personnel and Property
    The President’s authority over foreign diplomatic personnel derives
    from his power, under Article II, § 3 of the Constitution, to “receive
    Ambassadors and other Public Ministers.” This provision is the basis of
    the President’s power to grant or withdraw recognition to foreign
    governments and their ministers, a power regarded as textually commit­
    ted to the Executive alone. See Jones v. United States, 
    137 U.S. 202
    , 212
    (1890); B aker v. Carr, 
    369 U.S. 186
    , 212-13 (1962).3 The President’s
    power to accept or reject a particular envoy has been beyond serious
    question since President Washington demanded the recall of Citizen
    Genet, the French Minister. In 1855, the Attorney General took the
    position that this right of reception, and therefore rejection, extends to
    “all possible diplomatic agents which any foreign power may accredit
    1A separate international legal question w ould be raised in the event o f a claim o f political asylum
    by one o f the individuals w hose d ep artu re is o rd ered . T h e U nited States is a party to the 1967
    Protocol R elating to the Status o f R efugees, Jan. 31, 1967, 19 U .S.T. 6223, T.I.A .S. 6577. This
    Protocol obliges us not to expel o r return a refugee to a territo ry w here his life o r freedom w ould be
    threatened on account o f his race, religion, nationality, m em bership o f a p articular social g roup o r
    political opinion. T h e P ro to co l defines "refugee" as a person w ho, ow ing to w ell-founded fear o f such
    persecution, is outside the co u n try o f his nationality and is unable or, ow ing to such fear, is unw illing
    to avail him self o f the protection o f that country.
    T h e re is no exception provided in th e P ro to co l w ith respect to diplom atic and consular personnel
    and, in practice, such personnel have been acco rd ed the benefits o f the C onvention.
    It w ould seem unlikely that any Iranian diplom atic o r consular personnel w h o rem ain officials o f
    the present g o vernm ent o f Iran, more than one year after its establishm ent, w ould have a reasonable
    fear o f persecution by that governm ent. N evertheless, such claim s are possible, and the U nited States
    should have a pro ced u re for assuring that expulsion will not v iolate our treaty obligations under the
    R efugee Protocol. A possible approach to this problem is described in Part III o f this m em orandum .
    2 W e note that th e analytical basis fo r th e conclusions set fo rth above and the reasoning set forth
    below is d raw n to a great extent from a series o f m em oranda from this O ffice to the A ttorney G eneral
    dating from N ovem ber o f 1979. W e w ould also note that w e use the term s diplom atic personnel and
    diplom atic pro p erty herein to include b o th diplom atic and consular personnel and property; for our
    purposes, legal distinctions am ong these classes are eith er irrelevant o r specifically noted.

    to the United States.” 7 Op. A tt’y Gen. 186, 209 (1855); 5 Moore,
    International Law Digest 15—19 (1906). It is recognized that the power
    to receive Ambassadors is a discretionary one which necessarily in­
    cludes the right to refuse to receive them, to require their departure,
    and to determine their eligibility under our laws. 4 Moore, International
    Law Digest 473-548 (1906).
    The President’s power to receive and expel foreign diplomatic per­
    sonnel is a power recognized to inhere in all sovereign nations by the
    1961 Vienna Convention on Diplomatic Relations, Apr. 18, 1961,
    23 U.S.T. 3227, T.I.A.S. No. 7502. The President’s power over diplo­
    matic property is a concomitant of his power over diplomatic personnel
    to the extent that its exercise relates to his recognition power and his
    power over the conduct of our foreign relations and is likewise recog­
    nized by the Vienna Convention. Under Article 22 of the Vienna
    Convention, this country has a duty to take “all appropriate steps to
    protect the premises of the mission against any intrusion or damage and
    to prevent any disturbance of the peace of the mission.” Article 45 of
    the Convention requires the receiving state to “respect and protect the
    premises of the mission, together with its property and archives,” and
    authorizes the sending state to entrust custody of the premises to a third
    state acceptable to the receiving state where the receiving state orders
    the recall of diplomatic personnel.
    Because diplomats and consuls who have been ordered to leave the
    United States have always complied, the President’s authority to order
    their departure and to enforce such orders has never been subject to
    judicial challenge. However, individuals have from time to time
    claimed diplomatic status and have asserted a resulting entitlement to
    immunity from judicial process. In these cases the courts have consist­
    ently acknowledged that determinations as to whether an individual
    was recognized by the United States as a representative of a foreign
    government were properly within the province of the Executive. A c­
    cordingly, the courts have held that certifications by the Department of
    State are conclusive as to the status, privileges, and immunities of
    foreign diplomatic personnel. In re Baiz, 
    135 U.S. 403
     (1890); Carrera v.
    Carrera, 
    174 F.2d 496
    , 497 (D.C. Cir. 1949). As discussed below, we
    believe an executive determination that an individual previously recog­
    nized as a diplomatic or consular representative had been declared
    persona non grata and was required to depart from the United States
    would be entitled to the same judicial deference under the rationale of
    these decisions. See A dam s v. Vance, 
    570 F.2d 950
     (D.C. Cir. 1978).
    II. Legal Constraints on the Exercise of the President’s Authority
    We have identified three types of authority which inform and poten­
    tially constrain the President’s exercise of his authority to declare per­
    sona non grata and to expel foreign diplomatic personnel other than
    209
    personnel accredited to the United Nations and to regulate the use of
    diplomatic property.4 The first and most directly relevant authority is
    international law, specifically the Vienna Convention on Diplomatic
    Relations. The second is federal statutory law, including the Immigra­
    tion and Nationality Act of 1952, 
    8 U.S.C. §§ 1101
     et seq. The third is
    the Due Process Clause of the Fifth Amendment of the Constitution.
    We will discuss each of these in turn.
    A. International Law
    1. Diplomatic personnel
    Under international law it has long been recognized that every sover­
    eign nation has the right to determine whether it will receive a diplo­
    matic envoy from another nation and whether it will continue to
    receive and conduct official business with an envoy who has been
    accepted.5 This right is reflected in Article 9 of the 1961 Vienna
    Convention on Diplomatic Relations, a codification in most material
    respects of prevailing customary international law on this subject. Arti­
    cle 9 provides that the receiving state may, at any time and without
    having to explain its decision, notify the sending state that any diplo­
    matic officer is persona non grata or that a nondiplomatic staff member
    is no longer “acceptable.” Following this determination, the sending
    state must either recall the person concerned or, “as appropriate,”
    terminate that person’s functions at the mission.6
    Once declared persona non grata, foreign diplomatic personnel do not
    automatically lose their diplomatic status or the diplomatic immunities
    to which they are entitled under international law. Under U2 of Article
    9 of the Convention, if the sending state “refuses or fails within a
    reasonable period to carry out its obligations” to recall or terminate the
    services of a diplomat declared persona non grata, “the receiving State
    m ay refuse to recognize the person concerned as a member of the
    mission.” (Emphasis added.) You have asked us whether this remedy
    spelled out in Article 9, permitting the United States to strip diplomatic
    personnel of their diplomatic status if they have not left this country
    *A s indicated below , the P resident’s p o w er to com pel the d eparture o f diplom ats accredited to the
    United N ations has been, subsequent to the ratification by the Senate o f the C onvention on the
    Privileges and Im m unities o f the U nited N ations in 1970, essentially the same as his pow er to expel
    diplom atic personnel accred ited to this co u n try . This O ffice cu rren tly has under consideration at the
    request o f the Legal A dviser o f the D epartm ent o f State the question w hether diplom ats accredited to
    the U nited N ations enjoy the same im m unity from application o f paragraphs (27) and (29) o f 
    8 U.S.C. § 1182
    (a) to their entering this co u n try as diplom atic personnel accredited to the U nited States possess
    by virtue o f 8 U .S .C §1102.

    *T he records o f the International L aw Com m ission reflect that the term ination o f functions option
    is intended to apply prim arily to persons w h o are nationals o f o r perm anently resident in the receiving
    state.
    210
    after a reasonable period of time7 subsequent to their being declared
    persona non grata is, in effect, the exclusive remedy of the President to
    enforce Article 9. Stated another way, the question is whether, consist­
    ent with the Vienna Convention, the President through his agents may
    forcibly expel foreign diplomatic personnel from the United States
    subsequent to their being declared persona non grata. We believe that,
    consistent with the Vienna Convention, the President may do so.
    It has long been customary for the sending states to withdraw diplo­
    mats voluntarily when those diplomats have been declared persona non
    grata. Thus, as indicated above, in American practice it has apparently
    never been necessary forcibly to expel such a diplomat. Although the
    Vienna Convention is silent on the question of the right of the receiving
    state forcibly to expel a diplomat after declaring him persona non grata,
    there is support in both customary practice and in the negotiating
    record of the Convention for the taking of this action by the receiving
    state following that determination. One authority cites the fact that the
    early cases reflecting this practice “are all described as cases of ‘expul­
    sion.’ ” 8 This authority comments further that the practice of request­
    ing recall replaced expulsions “in the more placid political climate of
    the nineteenth century.” 9
    We believe that this history suggests why the Vienna Convention
    itself does not specifically spell out the right of a receiving state
    forcibly to expel a diplomat. We would add that H2 o f Article 9, read
    literally, does not purport either to require the receiving state to strip a
    foreign diplomat of his diplomatic status in this situation or suggest that
    remedy is the receiving state’s exclusive remedy to deal with a situation
    in which the sending state has not fulfilled its clear obligation under
    Article 9 to withdraw its diplomat or to itself terminate the person’s
    diplomatic status. Nothing in logic supports the proposition that we
    should assume the right to expel was abandoned as a matter of custom­
    ary international law even though it was not specifically spelled out in
    the Vienna Convention.10 In this connection, we note that the preamble
    to the Convention affirms “that the rules of customary international law
    should continue to govern questions not expressly regulated by the
    provisions of the present Convention.” The Vienna Convention, by
    remaining silent on the question of expulsion, in no way precludes a
    receiving state from taking this action.
    The position of the United States delegation to the United Nations
    Conference which drafted the Convention reflects the understanding of
    the U.S. government that a receiving state may require the departure of
    7T he drafting history o f A rticle 9 o f the C onvention indicates that the “reasonableness” o f the
    period follow ing a persona non grata action is largely dependent on the attendant circum stances. These
    circum stances may be such as to w arrant the receiving state’s dem and for im m ediate action.

    a member of the diplomatic mission. In commenting on the question of
    allowing a “reasonable period” in which the sending state must act
    following a persona non grata determination, the delegation stated: “[I]n
    aggravating circumstances, or where national security is involved,
    the receiving State may demand his [the diplomat’s] immediate
    departure. . . . ” (Emphasis added.)
    Further evidence of the United States’ interpretation of customary
    international law and the practice of the government with respect to
    the expulsion of diplomats is found in the testimony of Department of
    State Legal Adviser Leonard Meeker before the Senate Foreign Rela­
    tions Committee which considered proposed ratification of the Vienna
    Convention in 1965. Referring to the provision of the Convention
    (Article 41) which requires persons enjoying diplomatic privileges and
    immunities to respect the law of the receiving state, the Legal Adviser
    stated: “[I]f the situation becomes serious enough, we would have to in
    certain cases perhaps require the departure of members of the diplo­
    matic missions as we have a right to require and will have that right under
    the Convention, ju st as we do now. ” 11 (Emphasis added.)
    Since 1965, the government has publicly voiced its views concerning
    the right to expel diplomats. For example, in its report issued regarding
    the ratification of the Convention on the Privileges and Immunities of
    the United Nations, the Senate Committee on Foreign Relations paid
    special attention to several reservations to the proposed Convention,
    one of which stated that:
    Persons who are entitled to diplomatic privileges and
    immunities under the Convention shall not be required to
    leave the United States otherwise than in accordance with
    the customary procedure applicable to members of diplo­
    matic missions accredited or notified to the United States.
    Ex. Rep. No. 17, 91st Cong., 2nd Sess. 5 (1970).
    On its face, this reservation clearly assumes the existence of a
    nonstatutory, presidentially controlled and supervised procedure for the
    expulsion of foreign diplomatic personnel. More importantly for present
    purposes, the Senate Committee went on to state in its report:
    As a final recourse, under the proposed reservation and
    present law, the United States can compel the departure
    from its territory of anyone declared persona non grata
    12
    " Exec. H. 88th C ong., 1st Sess. 9 (1965).
    12 W e note that in the report to the President from the Secretary o f State o f N ovem ber 6, 1969,
    recom m ending transm ittal o f the C onvention to the Senate for advice and consent to ratification, the
    term s “com pel” and ’‘d e p artu re ,” ' ‘expulsion” and “ expelled” are used interchangeably. F urtherm ore,
    that rep o rt contains no reference w h atso ev er to the Im m igration and N ationality A ct, w hich was
    apparently assumed not to apply to this issue at all.
    212
    Thus, it is unquestioned that the United States has traditionally main­
    tained, and continues to maintain, the legal position consistent with
    prevailing rules of international law and practice and the Vienna Con­
    vention on Diplomatic Relations, that the receiving state has the right
    to require the departure, following persona non grata action, of alien
    nonresident members of the staff of a diplomatic mission.13
    An argument that a diplomat may not be forcibly expelled by a
    receiving state could be made based on the principle articulated in
    Article 29 of the Vienna Convention that the “person of a diplomatic
    agent shall be inviolable” and that such a person “shall not be liable to
    any form of arrest or detention.” We are not persuaded by that argu­
    ment for several reasons. First, these provisions of Article 29 cannot
    and have not been read to mean that a diplomat’s movement is not
    subject to any control, see Article 26 of the Vienna Convention, or that
    he cannot be prevented from taking action which violates the domestic
    law of the receiving state. [1957] 2 Y.B. Int’l L. Comm’n. 138.14 For
    example, the Department of State has taken the position that foreign
    diplomats may be escorted off the New Jersey Turnpike when found to
    be speeding, even though they were clearly not subject to arrest for
    that offense.15 We assume there would be no doubt that a foreign
    diplomat could be physically restrained from committing an assault on
    the streets of Washington, D.C., even though once again not subject to
    arrest for that assault, and that action could be taken without raising
    any substantial question under the Vienna Convention. In our view, an
    order of the President declaring foreign diplomats persona non grata
    with an accompanying order to depart the United States constitutes a
    legal determination under United States law that may be enforced in
    similar fashion so long as the foreign diplomat affected is treated “with
    due respect” as provided in Article 29.16
    Under the analysis above, we believe the President has the constitu­
    tional power forcibly to eject diplomatic personnel declared by him to
    13     International law w ith respect to the treatm ent o f consular officers and consular staff parallels
    that w ith respect to diplom ats; A rticle 23 o f the V ienna C onvention on C onsular Relations contains
    language nearly identical to that o f paragraphs 1 and 2 o f A rticle 9 o f the V ienna C onvention on
    D iplom atic Relations. U nder this A rticle the receiving state may declare a consular officer persona non
    grata o r a staff m em ber unacceptable and may w ithdraw recognition o r cease to consider the person as
    a m em ber o f the consulate if the sending state refuses to recall the person o r term inate his functions
    “ w ithin a reasonable tim e.” T h e official records o f the U N C onference w hich adopted this article
    clearly reflect the intention to prescribe rules relating to the determ ination that a m em ber o f a
    consulate is persona non grata o r no longer acceptable w hich are virtually the sam e as those relating to
    members o f a diplom atic mission. T he conferees specifically rejected proposals w hich w ould place
    consular personnel in a m ore advantaged position vis-a-vis diplom atic personnel. Thus, w e conclude
    that consular personnel may similarly be required to depart the receiving state follow ing persona non
    grata action. I Official R ecords UN C onference on C onsular R elations 209-217.

    16W e believe the phrase “due respect” must be read to authorize the use o f the minimum level o f
    force necessary to deal w ith any resistance by diplom atic personnel to their expulsion. Likew ise, that
    phrase in no w ay precludes personnel enforcing a presidential o rd e r from using reasonable force to
    defend them selves from violent acts against their persons.
    213
    be persona non grata from the United States and that the exercise of that
    power would be consistent with international law.
    2. Diplomatic property
    The President has sole power to recognize foreign countries and to
    determine the acceptability of their ministers; inherent in this authority
    is the implied power to control physical access to embassy premises in
    the United States. This includes the power to take necessary action to
    protect embassies from damage, and the power to deny possession to or
    eject those not recognized as diplomatic personnel of the sending state.
    As with the expulsion of diplomatic personnel, an argument can be
    made that the President’s power over the physical premises of diplo­
    matic properties is limited by the principle set forth in Article 22 of the
    Convention that the premises of an embassy are “inviolable.” This
    principle of inviolability is generally taken to mean that agents of the
    United States may not enter without consent of the head of the mission.
    At the same time, Article 22 imposes a duty on the receiving state to
    take “all appropriate steps to protect the premises of the mission against
    any intrusion or damage and to prevent any disturbance of the peace of
    the mission.”
    Article 45 of the Convention, however, modifies these commands
    somewhat in cases where, as here, the diplomatic personnel are tempo­
    rarily recalled. It requires the receiving state to “respect and protect
    the premises of the mission, together with its property and archives,”
    and authorizes the sending state to trust custody of the premises to a
    third state acceptable to the receiving state.
    It is plain from the background of the Convention that the duty in
    Article 45 to “respect and protect the premises” does not mean full
    inviolability. Denza, supra, at 281. Although it is not clear when invio­
    lability ends, analogy to our discussion above of Article 29 regarding
    termination of personal immunity suggests that inviolability should con­
    tinue for a reasonable time after the premises cease to be used for
    diplomatic purposes. In turn, this suggests that if the premises are used
    for purposes incompatible with a diplomatic mission, such as an armed
    occupation, inviolability should cease at that point. In view of this, the
    Convention’s provisions in Articles 22 and 45 protecting the integrity of
    the embassy premises suggest ample authority to control access to
    diplomatic property in these circumstances.
    B. Federal Statutory L aw
    1. Diplomatic personnel
    The President’s exclusive power over foreign diplomatic personnel as
    a matter of domestic law is explicitly and implicitly recognized in the
    214
    statute most directly relevant to the issues at hand, the Immigration and
    Nationality Act of 1952. Under § 102 of that Act, 
    8 U.S.C. § 1102
    ,
    diplomatic personnel are generally exempt from the provisions of the
    Act “relating to ineligibility to receive visas and the exclusion or
    deportation of aliens.” The legislative history of § 102 indicates clearly
    that the Congress, in leaving these matters to the President, was simply
    recognizing the constitutional limitations on its ability to control or
    regulate the President’s constitutional power to receive (and expel) the
    foreign representatives of countries with whom we have diplomatic
    relations. See H.R. Rep. No. 1365, 82nd Cong., 2nd Sess. 34 (1952).
    We believe this congressional recognition of the President’s exclusive
    power to deal with foreign diplomatic personnel is relevant to a deter­
    mination of the extent to which foreign diplomatic personnel, between
    the time they are declared persona non grata and the time they depart
    the United States or are forcibly expelled from the United States, may
    assert some legal entitlement to remain in the United States under the
    Immigration and Nationality Act. We do not believe they have any
    such entitlement during that period.
    Both immigrant and nonimmigrant aliens, whether in this country
    legally or illegally, are generally entitled to claim various rights to
    remain in this country should it otherwise be determined that they are
    deportable. Indeed, § 241(e) of the Immigration and Nationality Act, 
    8 U.S.C. § 1251
    (e), recognizes that diplomatic personnel who fail to main­
    tain their status as diplomatic personnel may not, when they lose their
    status, be required by the Attorney General to depart the United States
    without the approval of the Secretary of State except under certain
    limited circumstances. Thus, the Immigration and Nationality Act rec­
    ognized that diplomatic personnel may lose their status and, in doing
    so, become legally entitled to assert other rights to remain in the United
    States. The question, however, is whether diplomatic personnel, so long
    as they are deemed by the President to retain that status, may claim
    statutory entitlements to remain in this country after they have been
    declared persona non grata and ordered to depart the United States.
    In addressing this issue, we would first note that a construction of the
    Immigration and Nationality Act which would permit foreign diplo­
    matic personnel having been declared persona non grata and ordered to
    leave the country to assert other legal rights to remain in this country
    and therefore, by virtue of the process to which they would be entitled,
    at the very least substantially delay their departure, would directly
    impinge on the President’s power under the Constitution to deal with
    diplomats and to conduct our foreign relations. Particularly where the
    order for foreign diplomatic personnel to depart is directly related to
    the conduct of important foreign relations, which it clearly would be
    with regard to Iranian diplomatic personnel, we believe there would be
    a strong presumption against implying that Congress, by statute, gave
    215
    such diplomatic personnel the means to frustrate a decision by the
    President. Cf. N arenji v. Civiletti, 
    617 F.2d 745
     (D.C. Cir. 1979) cert,
    denied, 
    446 U.S. 957
     (1980). Generally, statutes should not be read to
    conflict with the Constitution, Crowell v. Benson, 
    285 U.S. 22
    , 62 (1932),
    treaties, United States v. Lee Yen Tai, 
    185 U.S. 213
    , 221-22 (1902), or
    the law of nations, Lauritzen v. Larsen, 
    345 U.S. 571
    , 578 (1953).
    As indicated above, § 102 of the Act, 
    8 U.S.C. § 1102
    , generally sets
    foreign diplomatic personnel apart from other classes of nonimmigrants
    for purposes of the Act. There would appear to be no judicial prece­
    dent regarding what rights foreign diplomatic personnel might have to
    interpose legal objections based on federal substantive law to their
    being expelled from the country on order of the President. One line of
    authority, however, dealing with persons paroled into this country
    pursuant to § 212(d)(5) of the Act, 
    8 U.S.C. § 1182
    (d)(5), supports our
    conclusion that foreign diplomatic personnel should be viewed as
    having no such rights.
    Under § 212(d)(5), the Attorney General is authorized to parole aliens
    into the United States under certain circumstances. Notwithstanding the
    fact that such parolees are physically within the United States, the
    Supreme Court has held that they are not entitled to assert any legal
    entitlement to remain in the country beyond the terms upon which they
    were paroled into the country even though, as a factual matter, they
    might otherwise qualify under the Immigration and Nationality Act to
    remain in the United States or at least to receive the Attorney Gener­
    al’s consideration of their claim to legal entitlement to remain in the
    United States. See Leng M ay M a v. Barber, 
    357 U.S. 185
     (1958).
    Although parolees, unlike foreign diplomatic personnel, do not tech­
    nically have “nonimmigrant” status, both classes of persons are phys­
    ically present in this country. In the case of parolees, the courts have
    determined that they have no entitlement to assert any legal right to
    remain in the country because they have not “entered” the country
    even though, as indicated above, they may be physically present not
    only at the border but indeed within the interior of the United States. A
    district court has summed up this concept of entry by stating that entry
    “means freedom from governmental restraint . . .             Klapholz v.
    Esperdy, 
    201 F. Supp. 294
    , 297 (S.D. N.Y. 1961). These cases clearly
    establish the proposition that the Constitution does not itself affect the
    power of the Congress or the President to effect the removal of some
    classes of persons within our physical borders summarily.
    In short, we do not believe that foreign diplomatic personnel have
    any statutory right to assert any legal entitlement to remain in the
    United States once they have been declared persona non grata and have
    been ordered to leave the country. This reading of the Immigration and
    Nationality A ct is consistent with and supported by the doctrine, dis­
    cussed supra, that statutes should be construed to avoid raising doubts
    216
    as to their constitutionality, Crowell v. Benson, 
    supra;
     Broadrick v.
    Oklahoma, 
    413 U.S. 601
     (1973). It is also consistent with the most
    recent expression by the Senate touching on this issue.
    In its report regarding the ratification of the Convention on the
    Privileges and Immunities of the United Nations, the Senate Committee
    on Foreign Relations paid special attention to several reservations to
    the proposed Convention, one of which stated:
    Persons who are entitled to diplomatic privileges and
    immunities under the Convention shall not be required to
    leave the United States otherwise than in accordance with
    the customary procedure applicable to members of diplo­
    matic missions accredited or notified to the United States.
    Ex. Rep. No. 17, 91st Cong., 2nd Sess. 5 (1970). On its face, this
    reservation clearly assumes the existence of a nonstatutory, presiden-
    tially controlled and supervised procedure for the expulsion of foreign
    diplomatic personnel. More importantly, for present purposes, the
    Senate Committee went on to state in its report (id.):
    As a final recourse, under the proposed reservation and
    present law, the United States can compel the departure
    from its territory of anyone declared persona non
    grata. . . .
    A separate question arises whether a foreign diplomat having been
    declared persona non grata and ordered to leave the United States could
    frustrate or delay the execution of that order either by himself renounc­
    ing his status as a foreign diplomat or having his diplomatic credentials
    revoked by his government. Although the issue is not free from doubt,
    we believe that neither the individual act of a foreign diplomat nor an
    act of the sending state which would substantially undermine the for­
    eign policy objective of the President should be permitted to do so.
    Thus, were the President to determine that the quick and sure expulsion
    of an identified group of foreign diplomats would significantly advance
    the foreign policy interests of the United States, we would not read
    either international law, i.e., the Vienna Convention, or domestic law,
    i.e., the Immigration and Nationality Act of 1952, as permitting the
    frustration of that foreign policy objective and the President’s constitu­
    tional authority to carry it out. Under Article 9 of the Convention,
    failure of the sending state to withdraw its diplomatic personnel in such
    situations specifically entitles the receiving state to strip the foreign
    diplomatic personnel involved of their status as diplomats. We see no
    logical reason to suggest that Article 9 does not implicitly recognize
    the power of receiving states to take action short of totally withdraw­
    ing that status and the immunities that accompany that status. As
    indicated in Part I of this memorandum, we believe the President
    constitutionally may do so. In this situation, the status of the diplomatic
    217
    personnel does not necessarily revert to one of being merely “illegal
    aliens” in the United States.
    This analysis also would apply, we believe, to a situation in which a
    foreign diplomat, rather than complying with a directive to depart the
    United States, went into hiding and was later found after the scheduled
    date for his departure had passed. In such a situation, we see no reason
    to recognize that act as bringing him within the protection of the
    Immigration and Nationality Act any more than a similar act commit­
    ted by a parolee. W hether Congress could constitutionally provide such
    protections for “ex-diplomats” is a question we need not address; we
    simply conclude that Congress has expressed no intent in the Immigra­
    tion and Nationality Act for such foreign diplomats to receive the
    benefits of the United States domestic law as a result of their defiance
    of an order issued by the President. Rather, Congress by its silence has
    left to the President the determination of when, for domestic law
    purposes, a foreign diplomat may lose that status and secure the benefits
    of our domestic law.
    Notwithstanding the clear constitutional power of the President to
    receive ambassadors and public ministers, their status as nonimmigrant
    aliens under the Immigration and Nationality Act may make it prudent
    for the Executive to take certain actions that might make it more
    difficult for a recalcitrant Iranian diplomat to challenge successfully the
    President’s decision in a federal court. Certain sections of the Act,
    particularly §§245 and 248, U.S.C. §§ 1255 and 1258 might be invoked
    as allowing a nonimmigrant to apply, as any other nonimmigrant may
    apply, to adjust his status or to change his classification. Since those
    sections entitle an alien “who is continuing to maintain” his nonimmi­
    grant status to make such applications, it would seem prudent for the
    Executive to use powers conferred by the Immigration and Nationality
    Act which might forestall this eventuality. Section 22 l(i) of the Immi­
    gration and Nationality Act, 
    8 U.S.C. § 1201
    (i), provides that after the
    issuance of a visa “the Secretary of State may at any time, in his
    discretion, revoke such visa or other documentation. Notice of such
    revocation shall be communicated to the Attorney General and such
    revocation shall invalidate the visa or other documentation from the
    date of issuance.” Thus, if the Secretary revoked the visas of diplomats
    who were declared persona non grata, the effect would be to cancel the
    diplomat’s nonimmigrant status, with the result that his arguable entitle­
    ment to adjustment would disappear.
    While termination of the status of a diplomat is rare in our practice,
    this is precisely what was done in 1961 in the case of Miroslav
    Nacvalac, a member of the Permanent Mission of the Czechoslovak
    Socialist Republic to the United States. The record indicates that prior
    to the revocation of Mr. Nacvalac’s status under § 101(a)(15)(G) of the
    Immigration and Nationality Act, 
    8 U.S.C. § 1101
    (a)(15)(G), he had
    218
    indicated an interest in discussing the possibility of remaining in the
    United States. In Press Release 421 dated June 21, the Department of
    State indicated that the effect of the revocation of Mr. Nacvalac’s
    status “is to place [him] in the category of an alien illegally in the
    United States of America.” The press release continued: “Under the
    laws and regulations of the United States of America, Nacvalac may
    elect to depart voluntarily or in lieu of such voluntary departure, be
    removed.” A footnote to the press release, which was reprinted in the
    Department of State Bulletin Vol. XLV, page 67, indicated that Mr.
    Nacvalac left the United States the next day.
    There have been only two decided cases in which a judge has
    confronted the question of visa revocation by the Secretary of State. In
    the first case there was no opinion. The second case, which was
    decided last year, is Knoetze v. United States, A ll. F. Supp. 201 (S.D.
    Fla. 1979), a f f d 
    634 F.2d 207
     (5th Cir.), cert, denied 
    454 U.S. 823
    (1981). In that case Judge Rottger of the United States District Court
    for the Southern District of Florida sustained the Secretary’s power to
    revoke visas. However, in his opinion he expressed concern that, when
    an alien whose visa was being revoked was in the United States, he did
    not have an administrative mechanism to insure that a revocation had
    not been erroneous. To meet this point, we believe that if it is decided
    for reasons of prudence to revoke visas of certain Iranian diplomats, the
    Department of State should establish an informal board of review to
    consider claims that revocation had been based on a mistake of fact.
    In summary, we believe that the President has the authority to
    require the removal from the United States of diplomats declared per­
    sona non grata. However, we believe that prudence dictates that in
    certain cases we should revoke the visas of such diplomats in order to
    forestall invocation of sections of the Immigration and Nationality Act
    as a basis for challenging the President’s decision. We believe that by
    using the revocation power, the government could demonstrate to a
    court that an objecting diplomat or consul had no colorable claim for
    relief under the terms of the Act.
    2. Diplomatic property
    Protection of embassy premises and diplomatic personnel is generally
    performed by the Secret Service’s Uniformed Division under 
    3 U.S.C. § 202
    , which provides that, subject to the supervision of the Secretary
    of the Treasury, the Division shall perform “such duties as the Direc­
    tor, United States Secret Service, may prescribe in connection with the
    protection of the following . . . (4) foreign diplomatic missions located
    in the metropolitan area of the District of Columbia; . . . and (8)
    foreign diplomatic missions located in such areas in the United States,
    its territories and possessions, as the President, on a case-by-case basis,
    219
    may direct. The members of such force shall possess privileges and
    powers similar to those of the members of the Metropolitan Police of
    the District of Columbia.”
    This statute first extended protection to diplomatic missions in 1970,
    in response to concern that the Metropolitan Police were providing
    inadequate protection against ordinary crime. Pub. L. No. 91-217, 
    84 Stat. 74
    . See generally S. Rep. No. 659, 91st Cong., 2d Sess. (1970). The
    extent of the “protection” that may be afforded is otherwise undefined
    in the legislative history. The ordinary meaning of the term suggests
    safeguarding the premises against damage or theft, and the personnel
    against assaults. The duty imposed on the United States by the Vienna
    Convention to protect mission premises even after the recall of the
    personnel strongly suggests that the Secret Service’s duties do not end
    with the sealing of a mission. Where recall is temporary, as here, there
    presumably must be a mission to which the personnel may return when
    relations improve. Thus, the Service has present duties to protect Ira­
    nian diplomatic property against third parties. These duties will extend
    to the consulates, however, only if the President so directs the Service.
    More difficult questions surround the power of the Service regarding
    nondiplomatic persons who assert the permission of the sending state to
    enter. Here, because the President has sole power to determine what
    governments and ministers are to be recognized, we believe there is
    implied power for the President to direct the Service to forbid access
    to* those not currently recognized as accredited diplomatic personnel to
    ensure that only those having diplomatic business with the embassy
    have access to it.
    Under 
    18 U.S.C. §970
    , damage or unauthorized occupancy of a
    diplomatic mission is a crim e.17 This provision, passed in response to
    terrorism at the Munich Olympics and elsewhere, is part of the “Act
    for the Prevention and Punishment of Crimes Against Internationally
    Protected Persons,” Pub. L. No. 94—467, 
    90 Stat. 1997
    . This statute
    17 (a) W hoever willfully injures, dam ages, o r destroys, o r attem pts to injure, dam age, or
    destroy, any property, real o r personal, located w ithin th e U nited States and belonging to
    o r utilized o r occupied by any foreign governm ent o r international organization, by a
    foreign official o r official guest, shall be fined not m ore th an $10,000, o r im prisoned not
    m ore than five years, o r bo th .
    (b) W noever, willfully w ith intent to intim idate, coerce, threaten, o r harass—
    (1) forcibly thrusts any p art o f him self o r any o bject w ithin or uport that portion o f any

    occupied fo r official business o r for diplom atic, consular, o r residential purposes by—
    (A ) a foreign governm ent, including such use as a mission to an international
    organization . . . ;
    (2) refuses to d ep art from such portion o f such building o r premises after a request—
    (A ) by an em ployee o f a foreign g o vernm ent o r o f an international organization, if
    such em ployee is authorized to m ake such request by the senior official o f the unit
    o f such g o vernm ent o r organization w hich occupies such portion o f such building or
    premises; . . .
    (D ) by anv person present having law enforcem ent pow ers;
    shall b e fined not m ore th an $500 o r im prisoned not m ore than six m onths, o r both.
    220
    surely provides authority for measures designed to protect the embassy
    against entry by anyone who has no permission from the government of
    Iran. Whether this ban can include those purportedly authorized access
    by the Iranian government but not recognized as accredited personnel
    by the United States may be less clear. Section 970 refers to 
    18 U.S.C. § 1116
    (b) for its definition of the foreign government whose premises
    are protected, and includes countries “irrespective of recognition by the
    United States.” The foreign officials entitled to demand that unauthor­
    ized persons depart the premises are defined, however, as those “duly
    notified to the United States as an officer or employee of a foreign
    government.” 
    18 U.S.C. § 1116
    (b)(3)(B). Thus, the statute appears not
    to authorize unaccredited foreign persons to demand the exit of others
    from diplomatic premises. When the accredited personnel have been
    expelled, this definition implies added scope to the authority under
    § 970(b)(2)(D) of “any person present having law enforcement powers”
    to order departure from the mission as necessary.
    This federal statute was not meant to “relieve any person of any
    obligation imposed by any law of any state, . . . or the District of
    Columbia.” H.R. Rep. No. 1614, 94th Cong., 2d Sess. 8 (1976). Because
    this statute was explicit in its refusal to preempt local criminal law, the
    Secret Service and the Metropolitan Police should have powers so
    conferred available to them. See Fatemi v. United States, 
    192 A.2d 525
    (D.C. Ct. App. 1963) (holding that Iranian students occupying the
    embassy against the wishes of the Minister could be convicted of
    “unlawful entry” under the D.C. Code).
    Finally, we believe that the Federal Bureau of Investigation (FBI)
    may participate in controlling access to diplomatic property under its
    general enabling authority, 
    28 U.S.C. § 533
    :
    The Attorney General may appoint officials—
    (1) to detect and prosecute crimes against the United
    States;
    (2) to assist in the protection of the person of the
    President; and
    (3) to conduct such other investigations regarding
    official matters under the control of the Depart­
    ment of Justice and the Department of State as
    may be directed by the Attorney General. . . .
    The presence of 
    18 U.S.C. §970
    , making unauthorized entries into
    diplomatic property a federal crime, is sufficient to invoke FBI jurisdic­
    tion under § 533(1).
    We would add that because actions taken to carry out the President’s
    order for diplomats to leave this country are incident to an exercise of
    his constitutional power, they neither rely on statutory authority for
    direct support nor are subject to the restrictions of the Posse Comitatus
    221
    Act, 
    18 U.S.C. § 1385
    , which generally restricts the use of Army or Air
    Force personnel to enforce civilian criminal law. In addition, 
    18 U.S.C. § 1116
    (d) specifically permits the use of military personnel from all the
    Armed Forces to enforce 
    18 U.S.C. §970
    . Thus, we believe that the
    President is entitled to call on the full range of his resources in the
    Executive Branch to achieve the objectives discussed herein. In addi­
    tion, § 1116(d) permits the President to draw on the resources of state
    or local law enforcement agencies in this situation.
    III. The Due Process Clause of the Fifth Amendment
    The final question presented by the expulsion of foreign diplomatic
    personnel from the country is whether the Due Process Clause of the
    Fifth Amendment requires that any kind of process be observed prior
    to their expulsion. This Office has previously taken the position that
    foreign diplomatic personnel derive their legal rights from their status
    as diplomats under international law. We believe the Due Process
    Clause is implicated, if at all, only with regard to the determination
    whether a person about to be forcibly expelled from the United States
    pursuant to an order of the President is in fact the person the President
    ordered to be expelled. Pursuant to our meeting of March 28, 1980,
    with representatives of the Department of State, we understand that a
    procedure reasonably calculated to ensure expulsion only of those per­
    sons previously ordered to be expelled by the President will be utilized.
    In these circumstances, we believe that the Due Process Clause, if
    applicable at all, would be fully satisfied and therefore we pretermit
    further discussion of that issue.18

    18 An issue related to the question of the applicability o f the Constitution to the forcible ejection of
    a foreign diplom at from the United States is the extent to w hich the order of the President w ould be
    subject to judicial review. Because a foreign diplom at being forcibly ejected w ould arguably be in the
    “custody” o f the President’s agents w ho w ere carrying out the President’s order to depart, there might
    be a colorable claim that a w rit o f habeas corpus pursuant to 
    28 U.S.C. § 2241
    (c)(4) w ould be
    available. U nder o ur analysis above, w e believe that the only claim upon w hich a w rit o f habeas
    corpus could even arguably be granted in this situation w ould be a claim that the person bringing the
    action is not in fact the same person as the foreign diplom at ordered to leave the country by the
    President. As indicated above, a procedure designed reasonably to ensure that such a mistake is not
    made should reduce litigation risks to the minimum.
