Immigration Mr. Peter Rees asked the Secretary of State for the Home Department what proof of identity and family relationship is currently required of persons seeking entry for settlement as dependent relatives; and what instructions have been given to entry clearance officers on this question. Mr. Alexander W. Lyon The entry clearance officer has to decide on the balance of probabilities whether the applicant is a dependant who qualifies under the Immigration Rules. Circumstances vary widely, but the officer may rely on any relevant documentary evidence as well as the interviews of the applicants and their witnesses carried out by himself or other officers. Instructions to posts are confidential.
