other than US taxes
There is also a requirement for US citizens to file a Report of Foreign Bank and Financial Accounts (FBAR) Google FBAR for the info. Basically, if you have more than $10,000 in foreign (non-US) banks, you have to file this report. And it is cumulative. $10,000 over various accounts. And it doesn't have to be your money. I have signature authority for my school Parents Counsel and have to include that amount. I would recommend contacting the US Consulate near you and ask them. they should have a person responsible for answering tax questions. My daughters have dual citizenship and have to deal with these problems. I would recommend counsel from an authority.
