Yes, in all cases your application must be countersigned. Someone who has known you personally for at least two years should complete and sign Section 10. That person should be a British Citizen, other British national or Commonwealth citizen who is a member of Parliament, Justice of the Peace, Minister of Religion, Bank Officer, Established Civil Servant, or professionally qualified person, e.g. Lawyer, Engineer, Doctor, School Teacher, Police Officer or a person of similar standing. Procedures include a check on the authenticity of the countersignatories.

If you do not know a British national or other Commonwealth citizen locally with these qualifications, a citizen of the country in which you are residing may complete and sign the form, provided they have a similar standing in that country and has known you for two years and the Consul considers their signature to be acceptable. A member of your family should not countersign. In certain cases you may be asked to produce further documentary evidence of identity.
