Hello all, I'm wondering the following: if a person lives outside the US but still has a US online brokerage account open, are there limitations or rules as to what investment instruments he/she is allowed to trade? I mean, the operation will go through as the website doesn't know you live abroad, but I was under the impression that one is not supposed to buy US stocks or stock funds directly from a US brokerage while living abroad, but rather one must go through an international brokerage account (many US brokerage firms do offer international accounts). Can anyone enlighten me?
