Leave to enter
According to the United Kingdom Border Agency, a person who is not a British citizen, a Commonwealth citizen with the right of abode in the UK, or a person who is entitled to enter or remain in the United Kingdom by virtue of the provisions of the 2006 EEA Regulations requires leave to enter the United Kingdom.
Leave to enter grants a person subject to immigration control permission to enter Britain for a limited period only, subject to a number of conditions:
(i) a restriction on employment or occupation in the United Kingdom;
(ii) a condition requiring the person to maintain and accommodate himself, and any dependants of his, without recourse to public funds; and
(iii) a condition requiring the person to register with the police.
The time limit of any Leave to enter depends upon individual circumstances and is provided to the applicant in person.
A person who has been granted leave to enter does not necessarily have the automatic right to enter Britain. The ultimate decision of entry is made by an Immigration Officer at the port of entry under paragraph 2A of Schedule 2 to the Immigration Act 1971.
