Immigration Act 1971

PART I Regulation of Entry into and Stay in United Kingdom

1 General principles

(1) All those who are in this Act expressed to have the right of abode in the United Kingdom shall be free to live in, and to come and go into and from, the United Kingdom without let or hindrance except such as may be required under and in accordance with this Act to enable their right to be established or as may be otherwise lawfully imposed on any person.

(2) Those not having that right may live, work and settle in the United Kingdom by permission and subject to such regulation and control of their entry into, stay in and departure from the United Kingdom as is imposed by this Act; and indefinite leave to enter or remain in the United Kingdom shall, by virtue of this provision, be treated as having been given under this Act to those in the United Kingdom at its coming into force, if they are then settled there (and not exempt under this Act from the provisions relating to leave to enter or remain).

(3) Arrival in and departure from the United Kingdom on a local journey from or to any of the Islands (that is to say, the Channel Islands and Isle of Man) or the Republic of Ireland shall not be subject to control under this Act, nor shall a person require leave to enter the United Kingdom on so arriving, except in so far as any of those places is for any purpose excluded from this subsection under the powers conferred by this Act; and in this Act the United Kingdom and those places, or such of them as are not so excluded, are collectively referred to as " the common travel area ".

(4) The rules laid down by the Secretary of State as to the practice to be followed in the administration of this Act for regulating the entry into and stay in the United Kingdom of persons not having the right of abode shall include provision for admitting (in such cases and subject to such restrictions as may be provided by the rules, and subject or not to conditions as to length of stay or otherwise) persons coming for the purpose of taking employment, or for purposes of study, or as visitors, or as dependants of persons lawfully in or entering the United Kingdom.

(5) The rules shall be so framed that Commonwealth citizens settled in the United Kingdom at the coming into force of this Act and their wives and children are not, by virtue of anything in the rules, any less free to come into and go from the United Kingdom than if this Act had not been passed.

(1) Except as otherwise provided by or under this Act, where a person is not patrial—

(a) he shall not enter the United Kingdom unless given leave to do so in accordance with this Act;

(b) he may be given leave to enter the United Kingdom (or, when already there, leave to remain in the United Kingdom) either for a limited or for an indefinite period;

(c) if he is given a limited leave to enter or remain in the United Kingdom, it may be given subject to conditions restricting his employment or occupation in the United Kingdom, or requiring him to register with the police, or both.

(2) The Secretary of State shall from time to time (and as soon as may be) lay before Parliament statements of the rules, or of any changes in the rules, laid down by him as to the practice to be followed in the administration of this Act for regulating the entry into and stay in the United Kingdom of persons required by this Act to have leave to enter, including any rules as to the period for which leave is to be given and the conditions to be attached in different circumstances ; and section 1(4) above shall not be taken to require uniform provision to be made by the rules as regards admission of persons for a purpose or in a capacity specified in section 1(4) (and in particular, for this as well as other purposes of this Act, account may be taken of citizenship or nationality).

If a statement laid before either House of Parliament under this subsection is disapproved by a resolution of that House passed within the period of forty days beginning with the date of laying (and exclusive of any period during which Parliament is dissolved or prorogued or during which both Houses are adjourned for more than four days), then the Secretary of State shall as soon as may be make such changes or further changes in the rules as appear to him to be required in the circumstances, so that the statement of those changes be laid before Parliament at latest by the end of the period of forty days beginning with the date of the resolution (but exclusive as aforesaid).

(3) In the case of a limited leave to enter or remain in the United Kingdom,—

(a) a person's leave may be varied, whether by restricting, enlarging or removing the limit on its duration, or by adding, varying or revoking conditions, but if the limit on its duration is removed, any conditions attached to the leave shall cease to apply; and

(b) the limitation on and any conditions attached to a person's leave may be imposed (whether originally or on a variation) so that they will, if not superseded, apply also to any subsequent leave he may obtain after an absence from the United Kingdom within the period limited for the duration of the earlier leave.

(4) A person's leave to enter or remain in the United Kingdom shall lapse on his going to a country or territory outside the common travel area (whether or not he lands there), unless within the period for which he had leave he returns to the United Kingdom in circumstances in which he is not required to obtain leave to enter; but, if he does so return, his previous leave (and any limitation on it or conditions attached to it) shall continue to apply.

(5) A person who is not patrial shall be liable to deportation from the United Kingdom—

(a) if, having only a limited leave to enter or remain, he does not observe a condition attached to the leave or remains beyond the time limited by the leave; or

(b) if the Secretary of State deems his deportation to be conducive to the public good; or

(c) if another person to whose family he belongs is or has been ordered to be deported.

(6) Without prejudice to the operation of subsection (5) above, a person who is not patrial shall also be liable to deportation from the United Kingdom if, after he has attained the age of seventeen, he is convicted of an offence for which he is punishable with imprisonment and on his conviction is recommended for deportation by a court empowered by this Act to do so.

(7) Where it appears to Her Majesty proper so to do by reason of restrictions or conditions imposed on citizens of the United Kingdom and Colonies when leaving or seeking to leave any country or the territory subject to the government of any country, Her Majesty may by Order in Council make provision for prohibiting persons who are nationals or citizens of that country and are not patrial from embarking in the United Kingdom, or from doing so elsewhere than at a port of exit, or for imposing restrictions or conditions on them when embarking or about to embark in the United Kingdom; and Her Majesty may also make provision by Order in Council to enable those who are not patrial to be, in such cases as may be prescribed by the Order, prohibited in the interests of safety from so embarking on a ship or aircraft specified or indicated in the prohibition.

Any Order in Council under this subsection shall be subject to annulment in pursuance of a resolution of either House of Parliament.

(8) When any question arises under this Act whether or not a person is patrial, or is entitled to any exemption under this Act, it shall lie on the person asserting it to prove that he is.

(9) A person seeking to enter the United Kingdom and claiming to be patrial by virtue of section 2(1)(c) or (d) or section 2(2) above shall prove it by means of such certificate of patriality as may be specified in the immigration rules, unless in the case of a woman claiming to be patrial by virtue of section 2(2) she shows that she is a citizen of the United Kingdom and Colonies and is patrial by virtue of section 2(2) apart from any reference therein to section 2(1)(c) or (d).

4 Administration of control

(1) The power under this Act to give or refuse leave to enter the United Kingdom shall be exercised by immigration officers, and the power to give leave to remain in the United Kingdom, or to vary any leave under section 3 (3)(a) (whether as regards duration or conditions), shall be exercised by the Secretary of State; and, unless otherwise allowed by this Act, those powers shall be exercised by notice in writing given to the person affected, except that the powers under section 3(3)(a) may be exercised generally in respect of any class of persons by order made by statutory instrument.

(2) The provisions of Schedule 2 to this Act shall have effect with respect to—

(a) the appointment and powers of immigration officers and medical inspectors for purposes of this Act;

(c) the exercise by immigration officers of their powers in relation to entry into the United Kingdom, and the removal from the United Kingdom of persons refused leave to enter or entering or remaining unlawfully; and

(d) the detention of persons pending examination or pending removal from the United Kingdom;

and for other purposes supplementary to the foregoing provisions of this Act.

(3) The Secretary of State may by regulations made by statutory instrument, which shall be subject to annulment in pursuance of a resolution of either House of Parliament, make provision as to the effect of a condition under this Act requiring a person to register with the police; and the regulations may include provision—

(4) The Secretary of State may by order made by statutory instrument, which shall be subject to annulment in pursuance of a resolution of either House of Parliament, make such provision as appears to him to be expedient in connection with this Act for records to be made and kept of persons staying at hotels and other premises where lodging or sleeping accommodation is provided, and for persons (whether patrial or not) who stay at any such premises to supply the necessary information.

5 Procedure for, and further provisions as to, deportation

(1) Where a person is under section 3(5) or (6) above liable to deportation, then subject to the following provisions of this Act the Secretary of State may make a deportation order against him, that is to say an order requiring him to leave and prohibiting him from entering the United Kingdom; and a deportation order against a person shall invalidate any leave to enter or remain in the United Kingdom given him before the order is made or while it is in force.

(2) A deportation order against a person may at any time be revoked by a further order of the Secretary of State, and shall cease to have effect if he becomes patrial.

(3) A deportation order shall not be made against a person as belonging to the family of another person if more than eight weeks have elapsed since the other person left the United Kingdom after the making of the deportation order against him ; and a deportation order made against a person on that ground shall cease to have effect if he ceases to belong to the family of the other person, or if the deportation order made against the other person ceases to have effect.

(4) For purposes of deportation the following shall be those who are regarded as belonging to another person's family—

(a) where that other person is a man, his wife and his or her children under the age of eighteen; and

(b) where that other person is a woman, her children under the age of eighteen ;

and for purposes of this subsection an adopted child, whether legally adopted or not, may be treated as the child of the adopter and, if legally adopted, shall be regarded as the child only of the adopter; an illegitimate child (subject to the foregoing rule as to adoptions) shall be regarded as the child of the mother ; and " wife " includes each of two or more wives.

(5) The provisions of Schedule 3 to this Act shall have effect with respect to the removal from the United Kingdom of persons against whom deportation orders are in force and with respect to the detention or control of persons in connection with ' deportation.

(6) Where a person is liable to deportation under section 3(5)(c) or (6) above but, without a deportation order being made against him, leaves the United Kingdom to live permanently abroad, the Secretary of State may make payments of such amounts as he may determine to meet that person's expenses in so leaving the United Kingdom, including travelling expenses for members of his family or household.

6 Recommendations by court for deportation

(1) Where under section 3(6) above a person convicted of an offence is liable to deportation on the recommendation of a court, he may be recommended for deportation by any court having power to sentence him for the offence unless the court commits him to be sentenced or further dealt with for that offence by another court:

Provided that in Scotland the power to recommend a person for deportation shall be exercisable only by the sheriff or the High Court of Justiciary, and shall not be exercisable by the latter on an appeal unless the appeal is against a conviction on indictment or against a sentence upon such a conviction.

(2) A court shall not recommend a person for deportation unless he has been given not less than seven days notice in writing stating that a person is not liable to deportation if he is patrial, describing the persons who are patrial and stating (so far as material) the effect of section 3(8) above and section 7 below ; but the powers of adjournment conferred by section 14(3) of the [1952 c. 55.] Magistrates' Courts Act 1952, section 26 of the [1949 c. 94.] Criminal Justice (Scotland) Act 1949 or any corresponding enactment for the time being in force in Northern Ireland shall include power to adjourn, after convicting an offender, for the purpose of enabling a notice to be given to him under this subsection or, if a notice was so given to him less than seven days previously, for the purpose of enabling the necessary seven days to elapse.

(3) For purposes of section 3(6) above—

(a) a person shall be deemed to have attained the age of seventeen at the time of his conviction if, on consideration of any available evidence, he appears to have done so to the court making or considering a recommendation for deportation ; and

(b) the question whether an offence is one for which a person is punishable with imprisonment shall be determined without regard to any enactment restricting the imprisonment of young offenders or first offenders;

and for purposes of deportation a person who on being charged with an offence is found to have committed it shall, notwithstanding any enactment to the contrary and notwithstanding that the court does not proceed to conviction, be regarded as a person convicted of the offence, and references to conviction shall be construed accordingly.

(4) Notwithstanding any rule of practice restricting the matters which ought to be taken into account in dealing with an offender who is sentenced to imprisonment, a recommendation for deportation may be made in respect of an offender who is sentenced to imprisonment for life.

(5) Where a court recommends or purports to recommend a person for deportation, the validity of the recommendation shall not be called in question except on an appeal against the recommendation or against the conviction on which it is made ; but—

(a) except in Scotland, the recommendation shall be treated as a sentence for the purpose of any enactment providing an appeal against sentence ; and

(b) in Scotland, a person recommended for deportation may, without prejudice to any other form of appeal under any rule of law, appeal against the recommendation in the same manner as against a conviction.

(6) A deportation order shall not be made on the recommendation of a court so long as an appeal or further appeal is pending against the recommendation or against the conviction on which it was made ; and for this purpose an appeal or further appeal shall be treated as pending (where one is competent but has not been brought) until the expiration of the time for bringing that appeal or, in Scotland, until the expiration of twenty-eight days from the date of the recommendation.

(7) For the purpose of giving effect to any of the provisions of this section in its application to Scotland, the High Court of Justiciary shall have power to make rules by act of adjournal.
