(i) a visa national;
(ii) any other person (other than British Nationals (Overseas), a British overseas territories citizen, a British Overseas citizen, a British protected person or a person who under the British Nationality Act 1981 is a British subject) who is seeking entry for a period exceeding six months or is seeking entry for a purpose for which prior entry clearance is required under these Rules.
Such a person will be refused leave to enter if he has no such current entry clearance. Any other person who wishes to ascertain in advance whether he is eligible for admission to the United Kingdom may apply for the issue of an entry clearance.
25. Entry clearance takes the form of a visa (for visa nationals) or an entry certificate (for non visa nationals). These documents are to be taken as evidence of the holder's eligibility for entry into the United Kingdom, and accordingly accepted as "entry clearances" within the meaning of the Immigration Act 1971.
25A. An entry clearance which satisfies the requirements set out in article 3 of the Immigration (Leave to Enter and Remain) Order 2000 will have effect as leave to enter the United Kingdom. The requirements are that the entry clearance must specify the purpose for which the holder wishes to enter the United Kingdom and should be endorsed with the conditions to which it is subject or wish a statement that it has effect as indefinite leave to enter the United Kingdom. The holder of such an entry clearance will not require leave to enter on arrival in the United Kingdom and, for the purposes of these Rules, will be treated as a person who has arrived in the United Kingdom with leave to enter the United Kingdom which is in force but which was given to him before his arrival.
26. An application for entry clearance will be considered in accordance with the provisions in these Rules governing the grant or refusal of leave to enter. Where appropriate, the term "Entry Clearance Officer" should be substituted for "Immigration Officer".
27. An application for entry clearance is to be decided in the light of the circumstances existing at the time of the decision, except that an applicant will not be refused an entry clearance where entry is sought in one of the categories contained in paragraphs 296-316 solely on account of his attaining the age of 18 years between receipt of his application and the date of the decision on it.
28. An applicant for an entry clearance must be outside the United Kingdom and Islands at the time of the application. An applicant for an entry clearance who is seeking entry as a visitor must apply to a post designated by the Secretary of State to accept applications for entry clearance for that purpose and from that category of applicant. Subject to paragrapgh 28A, any other application must be made to the post in the country or territory where the applicant is living which has been designated by the Secretary of State to accept applications for entry clearance for that purpose and from that category of applicant. Where there is no such post the applicant must apply to the appropriate designated post outside the country or territory where he is living.
28A. (a) An application for entry clearance as a Tier 5 (Temporary Worker) Migrant in the creative and sporting sub-category of Tier 5 may also be made at the post in the country or territory where the applicant is situated at the time of the application, provided that:
(i) the post has been designated by the Secretary of State to accept applications for entry clearance for that purpose and from that category of applicant,
(ii) the applicant is in that country or territory for a similar purpose to the activity he proposes to undertake in the UK, and
(iii) the applicant is able to demonstrate to the Entry Clearance Officer that he has authority to be living in that country or territory in accordance with its immigration laws. Those applicants who are known to the authorities of that country or territory but who have not been given permission to live in that country or territory will not be eligible to make an application.
(b) An application for entry clearance as a Tier 5 (Youth Mobility Scheme) Temporary Migrant may also be made at the post in the country or territory where the applicant is situated at the time of the application, provided that:
(i) the post has been designated by the Secretary of State to accept applications for entry clearance for that purpose and from that category of applicant, and
(ii) the applicant is able to demonstrate to the Entry Clearance Officer that he has authority to be living in that country or territory in accordance with its immigration laws and that when he was given authority to live in that country or territory he was given authority to live in that country or territory for a period of more than 6 months. Those applicants who are known to the authorities of that country or territory but who have not been given permission to live in that country or territory will not be eligible to make an application.
29. For the purposes of paragraph 28 "post" means a British Diplomatic Mission, British Consular post or the office of any person outside the United Kingdom and Islands who has been authorised by the Secretary of State to accept applications for entry clearance. A list of designated posts is published by the Foreign and Commonwealth Office.
30. An application for an entry clearance is not made until any fee required to be paid under the Consular Fees Act 1980 (including any Regulations or Orders made under that Act) has been paid.
30A. An entry clearance may be revoked if the Entry Clearance Officer is satisfied that:
(i) whether or not to the holder's knowledge, false representations were employed or material facts were not disclosed, either in writing or orally, for the purpose of obtaining the entry clearance; or
(ii) a change of circumstances since the entry clearance was issued has removed the basis of the holder's claim to be admitted to the United Kingdom, except where the change of circumstances amounts solely to his exceeding the age for entry in one of the categories contained in paragraphs 296-316 of these Rules since the issue of the entry clearance; or
(iii) the holder's exclusion from the United Kingdom would be conducive to the public good.
30B. An entry clearance shall cease to have effect where the entry clearance has effect as leave to enter and an Immigration Officer cancels that leave in accordance with paragraph 2A(8) of Schedule 2 to the Immigration Act 1971.
30C. An Immigration Officer may cancel an entry clearance which is capable of having effect as leave to enter if the holder arrives in the United Kingdom before the day on which the entry clearance becomes effective or if the holder seeks to enter the United Kingdom for a purpose other than the purpose specified in the entry clearance.
