Visas to the UK - general
When completing the application form, must I always provide the name of a British Citizen as a sponsor?
No. Anyone present in the United Kingdom, for whatever purpose, can sponsor someone. It is, however, important to name the specific sponsor particularly in the case of family visits. If you are intending to visit your relative then please specify this and submit evidence of their immigration status in the UK (eg a copy of their passport photograph page and current UK Visa).
