We've been invited by a friend to visit the UK for 2 weeks. Our visas, return air fare, accommodation (we will stay at a house he owns) and all other expenses (food, travel within the UK, tickets to attractions etc.) will be borne by our friend, who's a UK citizen. We're Indian nationals and will have to attend an interview in Bangalore as part of the process.
Apart from a letter of invitation, what other documents will our sponsor need to provide? By documents I mean government IDs, bank statements, proof of ownership of his house etc.
Also, do these documents have to be sent directly to the High Commission by our sponsor, or do we submit these to the officer during the interview for the visa in Bangalore?
P.S We = Me and my mother (who's 70+). Both of us hold Indian passports.
