Thank you for your insight
We're planning to port our US phone number with google, and already have GV number for backup for SMS one time password. GV number works with both Fidelity & Schwab, already tried it
Yes Fidelity will not let you buy mutual fund which not a problem for us as we're normally trading only ETF. I will have to check with them again just to confirm for sure that I can change the address online by myself once in thailand.
We can't call Schwab yet because we still have TD Ameritrade account. The merger between 2 companies won't be completed until Sept 5 this year
For regular banking - we open account with Navy Federal and they said they won't close our account when we live in Thailand, and can do regular banking functions normally. My wife called and emailed to them to reconfirm this twice already. I'm not in a navy but as long as you know somebody in military they will let you open an account with them, so that's how we did it.
We rather not keeping our US condo, just want to sell it and have a clean move. Also we're not in retirement age yet to withdrawal our social security, so we need the US house proceed to buy a new one in thailand. We don't have any relative in the US, I'm not from the US and my wife is Thai. We want to move because this country is getting crazier and crazier by everyday
