I am looking to travel to the UK (Britain) to visit my fiancée. I have the passport and I am getting the funds for the visa and the trip. But I am not completely sure how much money I would need to actually be allowed in. I am looking to stay for about a month and a half to two months. I was already turned away at the door for not having enough funds with me, so I don't want to make that mistake again and waste another 1,800 for airfare only to get told I can't get in.
So please if someone could tell me at least the range of how much money I would need to get the Standard Visitors visa and to be able to get into the country. I will be staying with my fiancée the entire time, so I won't be needing funds for room and board and such.
What do I need to bring, both in documentation and in funds?
