I’ve made investments in the stock market; is that a problem?
The US has made investing in the stock market outside the US. extremely complex. Banks abroad are denying US Citizens investment services for fear of a penalty due to FATCA. Buying individual stocks might be possible whereas buying funds outside the US poses a big problem. The US also imposes a non creditable taxation on some investment products abroad.
The US furthmore requires that you report all financial interest you have in the US or abroad (FBAR). The US regulations on reporting these investments are complex. Therefore, we advise you to have this screened by a tax advisor specialised in filing for US citizens abroad. Americans Overseas can provide you with names of professionals if desired.
