学生有绿卡还可以用8833表格申请中美tax treaty的5000刀退税吗

如题所述。。。。。。。。。。

不可以，只有f1/j1可以claim tax treaty。与是不是ra无关，而且treaty可以apply on top of standard deduction的

只要是F1身份（包括OPT）就可以用treaty，与是不是Resident无关。如果有绿卡了就不是F1了，应该是不能再用了。但是如果是双重身份，比如1-6月是F1，7月拿到绿卡后F1失效，那前6个月的收入还是可以用treaty。下面是原文from IRS：
A student from the People's Republic of China is also entitled to the $5,000 exemption each year for the amount of time reasonably necessary to complete education or training. Students will become resident aliens for tax purposes after five years, but would still be entitled to the treaty benefit as long as they remain students.

standard deduction 不比 5000 更多吗

只有Non resident alien才能用吧？绿卡是resident alien

不可以的。
