we're in the same position of considering moving back to the US (we're both USCs now - thank god OH had the foresight to do that before we left - I didn't even think of it!). But we know we should wait until I get my UKC (2015 as well). You never know how you will feel down the road, and perhaps this is a bad reason, but I can't help but think 'what if i develop some chronic disease' that will bankrupt me in the US'? Or 'what if we'd like to retire some place in Europe'?
3 years, I believe, will really fly by, and there must be things you and hubs can do within this time period to bolster your career? OH continues to freelance for his job in NYC to keep his network and US skills alive. I'm hoping to start a pilates studio at some point and currently know nothing about business so I'm going to focus on teaching, learning new related skills, learning about starting a business, and try my luck in networking here to initiate new programs with PT practices...etc. (might as well try - got nothing to lose, really, and I'll be practicing business skills/partnerships!). OH! and we've got a little one due next month to keep us busy - ha!
it always takes awhile to settle any place new, so I'd say give it some time and reassess the situation every 6 months.
keep us posted on your decision! it's nice to have found some people in a similar situation (though I'm sorry you're going through it as well!).
