I (31M) am an American serving in the US military and I have been stationed in the UK for several years. My contract is coming to an end in a few months and I have just secured a very lucrative job offer (£170k!) and the employer is offering to sponsor me for a work visa. From what I understand, I won't need to return to the US first, I can start work right away once I'm discharged.

With this offer, and after several years of consideration, I've decided I want to remain in the UK permanently after I'm discharged and eventually apply for British citizenship.

I currently have about $87k in assets (Roth IRA, savings, etc.) and I'm not sure how I can transfer these assets to GBP (or even if I should ) and if there are any tax implications, penalties or otherwise.

If there is a more appropriate subreddit for these sorts of questions, please let me know.

Otherwise, my questions are:

What's the easiest way to transfer my USD assets to GBP?

If I can't transfer my USD retirement accounts to GBP, is it possible…
