About visiting relatives visa

Boyfriend and girlfriend are not registered to get married and are not relatives, so they can't apply for a visit visa. However, you can apply for a tourist visa.

Invitations can be sent between friends. Since his girlfriend is in Britain, it is easier to apply for a tourist visa than for a pure tour.

If you stay, say that he used to live with you. Boyfriends and girlfriends are very close, and it is normal to live together.

When applying for a visa, you don't need to write too long for leave. At present, all tourist visas issued by the UK are valid for six months and can be made for multiple trips.
