So, I'm looking for some advise. My partner lives in the USA, myself on the UK. We have been dating for almost 3 years now, birthday cards, anniversary cards, talk almost daily, I've visited the states twice to spend time with him in person - and we think were ready to accually get married and move to be with each other.

Looking at the process - it looks relatively easily. My consern is proof. How do you prove a relationship (self applying).

We obviously have messaged logs, call logs (calls that can sometimes last hours), I can prove jy trips to the states (flights/hotel bookings/spending in the states). But that's kinda it. Could probably get affidavids from friends to who know about our relationship, at least one us based friend that's mutual and one UK friend. Would this be enough if not what else it recommended?

Thanks hope to get some advise.
