This post features an interesting Facebook discussion. The reality of life for many Americans abroad is two-fold:
1. It is common for Americans abroad to marry non-U.S. citizens;
2. Americans abroad are (with few exceptions) required to report to U.S. Financial Crimes (Think Mr. FBAR) bank accounts that they either have signing authority over or where they can control the disposition of the funds.
The reality is that, in the case of joint accounts, this means that the U.S. citizen will report the bank accounts of the spouse to the U.S. Government. Different people have different views of this.
The Facebook discussion referenced in the above tweet is very interesting.
