It can be a huge hassle for normal US citizens living outside the US. Most banks won&#x27;t deal with them because of the risks involved. As a US citizen abroad, just getting a regular bank account can be next to impossible.<p>I live in Singapore and when I was signing up for a stock trading account I asked what would have happened if I had to answer yes in the box that asked if I was liable to pay income tax in the US. The answer was plain: &quot;you wouldn&#x27;t be allowed to have an account with us&quot;.
