回複：Mother visited me. Does anybody know how to apply TAX ID f

It's easy. But she has to stay over 180 days to qualify the program.

Just go to irs website, download the form and file to Philidaphia. Note to notorize your mother's visa. This is very important. otherewise, it could take more than half of year to get it down. The normal response from IRS takes 8 weeks!

Good luck!
