把护照寄回来填W-7然后公正

请问能不能给点细节，如何claim来探亲的父母as dependent, 偶朋友也是父母来了半年多，正好不知道如何报税，请不吝赐教。

If the parents of your friends stay at US longer than 183 days, they can be claimed as your friend's dependent and need to apply for their ITINs.

1.File Form W7 (you can get the form from your local IRS office or download it from IRS website).
2.Following the instruction on the W7, usually it needs copies of both parents' passports (notarized) and their signature.
3.Attach the complete form W7 and requested documents with their current tax return (usually it's form 1040), send them to the designated address (not the address to file your tax return).
4.Once they are approved, the parents will get their ITIN, and the form 1040 will be forwarded to the IRS tax return department.

不用寄原件，在国内做公证然后把公证书寄过来就好了吧
噢，还要把父母签过字的w7寄过来
