Thanks for the replies.
I've been over a lot in the last two years. I feel like I've done the grand tour of the City a few times over in search of good craft beer, bbq, and mexican food - essentially the holy trinity of being from Texas. So far I've been disappointed, but I've enjoyed the quest just the same and it will go on.
I'll skip the wig and have my tailoring done a bit further down the street from Ravenscroft. It's actually really difficult as a lawyer to transfer in as a barrister, versus just taking a couple (hard) tests for solicitor. But, I'm going to be doing something more like intl transactional work for a city firm. I can't imagine any reason I'd be inside a courtroom unless I witnessed a crime or something.
re: Getting her a greencard.
Our plan is to live/work in London for 5-6yrs. After that, I likely need to come back to the US to make partner - it is more lucrative that way & many firms are on a verein structure so it matters. After partner, we'll likely split time.
Initially, the greencard wouldn't serve a huge purpose other than perhaps ease of entry to the US. My fear is, there is an ongoing trend of UK firms acquiring US firms or expanding further into US markets. I could easily see my UK firm telling me to go to a new US office to help integrate or jump start it. I wouldn't want something like that to happen and have her stuck in England waiting on paperwork to join me. We've done enough of the long distance thing and are not keen to do it again after we're married. Really I'd like full freedom of movement/employment for both of us in both places.
re: fiance visa... I'm aware I cannot work on one. Theoretically that should not be an issue. I am taking the July bar in the US so I likely won't be working till after that is done, then we're planning to be married in Aug. If I were to need to start work before the marriage then the firm is well able to sort a work visa. I realize there can be some timing and complexity issues, but I cannot plan for every possible eventuality. We just have to cross those bridges as they come.
My bigger concern of the moment is meeting the financial requirement. She's working a couple internships and some minor freelance work, and not even for six months. Reading the rules, it looks like to meet the requirement from pure savings would necessitate holding 62,500 in savings in her name for six months before we submit the application. I hate to make her do that, but we can if that's what we have to do. It just seems excessive to an 18,600 income requirement.
