Hi
It is perfectly acceptable to buy tickets before getting your visa. As you say it can be evidence of intent to return.
Thank you for the clarification. After having fully read the guidance document I mentioned above, I always knew that they recommend not buying tickets, but didn't know if they ever counted it as a mark against someone if they did buy the tickets. So it sounds like they don't.
To me that would really make sense and would strengthen someone's case for the visa, rather than weaken it. Why would someone buy a ticket that costs thousands upon thousands of dollars, yet just stay in the UK? That they wouldn't see that as an intent to return is beyond strange to me, and has no basis in reality.
On a related note, since I never got this question answered elsewhere, when the application asks "What is the cost to you personally of your stay in the UK?", is it asking about just accommodation, food and ticket prices, or also the full cost of all wedding related expenses as well? I was a little unsure on that, as my wedding expenses are much much higher than my accommodation and travel expenses, but if I don't have to list them I'm not going to. What does everyone else do, or what is acceptable for that matter?
Thank you very much again to everyone.
