My suggestion would be to work where you can to earn money, then come back to Taiwan to spend it. I pretty much do this. The accountant at my previous company did the same. With your background, you should be looking at project/contract work rather than a 9-to-5 anyway. True, you'll be separated for, what, 50% of your lives, but IMO that's not necessarily a bad thing
. Obviously, she could join you while you're working whereever, although air fares are likely to make a big dent in your savings.
And sell the car regardless. Cars are a waste of money.
