I'd like to invite a friend to the UK on a Standard Visitor Visa. We both hold Indian passports. I have a Tier 4 (General) UK visa and he is in a doctoral programme in France and has a Titre de Sejour. When I invited him the last time, in addition to my proof of student and immigration status, we had submitted my contract as proof of accommodation. He was granted a multi-entry visa and visited four times within the six months of its validity.
For the present application, my contract expires on 1st October, but I had a verbal agreement with the landlord that I can continue living there on the same terms for a few more months, but we haven't signed a new contract.
As with any document, submitting an expired contract sounds like a bad idea. What are my options?
