Hi, My family visit visa is under my current passport which is still has my maiden name on it. The visa expires on December 2014. I will be renewing my passport next month and will change to my married name. Question is, will my visa still be valid or do I have to re-apply? Thanks
I would think you'll be fine but it might be a good idea to carry a copy of your Marriage Certificate to show the Immigration Officer when you arrive in the UK.
Your visa will still be valid till its expiry date. Just keep and travel with both old and new passports. Same for my wifes spouse visa. She has a new passport with her married name in. She just has to take her old passport with her along with the new.
