Streamlined Foreign Offshore Procedure For Us Expats For many US citizens born outside the US, or who left with their families at a young age, they don't realize that they need to file US tax returns each year. One of the main hurdles for that is that you need a social security number (SSN) to file the returns with the IRS.
Social security number and card If you don't have a social security number, you can apply at your nearest US Embassy or SSA offices. Even if you had a SSN before, the tax office can provide a replacement social security card. Once you have the SSN card, then you can move on to be compliant with your US taxes.
