F1 file jointly，但我是F1 nonresident被扣了medicare和social security tax，到
底该不该退这个税，填843？
看了精华关于F1 file jointly 不影响另一方NR退medicare和social security tax。
不知道这个帖子是什么时候的，里面只说根据2005年的条款。
我看了现在的条款，
1）Election to File Joint Return
If you make this choice, you and your spouse are treated as residents for
your entire tax year for the purpose of your federal individual income tax
return, and for the purpose of withholding U.S. federal income tax from your
wages. 这里只提到了federal individual income tax, 请问包括medicare和social
security tax吗？
2)Aliens Employed in the U.S. – Social Security Taxes
F1免除这个税，但是有exception。这里说tax purposes是不是包括所有？
The exemption does not apply to nonimmigrants in F-1,J-1,M-1, or Q-1/Q-2
status who become resident aliens for tax purposes.
