@pk, sorry for the delay in my response. Here are the answers to the questions you asked:
a. Thailand
b. No
c. New York
d. Only one such account: an account that was and is still jointly-owned
e. Well, she had gone to the local US consulate to ask questions and options. She was told that she would have significant trouble entering the US, as it had been about 18 months since she had last entered and would be another six before she would try to enter again (2 years, all told). I am not sure that the information she was given was correct, but, in any case, after fair investigation and consternation, she returned to the consulate to abandon her GC, and apply immediately for a tourist-visa, so that she'd have no trouble entering the US on her next visit. We hadn't heard of that 3-year-waiver you mentioned. In any case, although I wish that she could maintain or regain it, it seems that it's now too late and that she must live with the tourist-visa.
f. No, now that I work overseas
