We got our fiancee visa!

I feel a little silly even asking this, tbh. And if it's not okay, please tell me! I want to be a good community member.
I thought waiting for that decision would be the hardest part of this foot of the journey, but due to anxiety and stress, both with getting my belongings sorted and a curmugeony family member on my side...
 I have this awful, sinking feeling I am forgetting something. Is there something else I need to apply for or do, before the FLR when we get married?
Please help

Congratulations!!! 

The main thing to do is get your name on as much mail as possible as soon as you arrive in the UK, you'll need that coming in regularly, actually on paper, for both of you for the next 5 years.

Safe journey! 

@larrabee So nothing to apply for or need to do before taking my flight?
(The other stresser is my cats arrangements but the company i chose has been fantastis so far)

Nothing visa wise.

Generally though, make sure you have a bank account and credit card still open in the US. Ideally, one which will deal with you as an expat. If they won't, change the statements to a parents address if you can.
I believe the US social security online account can only be made with a US address, you look like you're a long way away from that but it won't hurt to open an account if you don't already have one.

Good luck with your kitty. We flew ours and they were just fine!

Oh and these threads are a bit dated but might still be worth a read.
