Hello, so sorry for the late reply!
I don't have firm plans for the future move - we are planning to move to another EU country while we still can, so we actually don't need too much to do that, as bringing a foreign spouse to another EU nation isn't too complex and you basically show up and register, so we don't have a ton of proof, so to speak, because we don't really need much. We're just having a lawyer sort out some documents, but we won't be doing it for a little bit yet.
For the tourist visa, I can at least show them a rental contract for my room and proof of funds to support myself with while in the UK and a round trip ticket, of course. It's frustrating, because I would never sneak in and stay illegally in a million years, all I want to do is visit my husband. Some people have even suggested flying into another part of the UK, because the immigration people often aren't as strict outside of London. Any thoughts?
