for medicare and social security tax withheld return.

问题来了

3a. type of tax,几个选项

#employment # estate #gife #excise #penalty-IRC section

应该是哪一种？

选 employment

还有

3b里提到的type of return filed,我都没有填过，我只有填过1040, 8843，IT203系列

偶曾经填过这个843表，但是是让别人填的，3b填的是941. you will have to attach form 941c, http://www.irs.gov/pub/irs-pdf/f941c.pdf

还有这份表要statement for explanation and additional claims.

不知道有没有xdjm们成功地figure out 这份表的填法

还有一个问题就是

我查了publication 519,因为我是在OPT

form 843，8816要和 Form I-766 or Form I-688B一起寄到国税局

但是， Form I-766 or Form I-688B 是employer authorization form,也就是说我要去问我的employer去要这两份表么？

i guess you have to ask for such forms. IRS probably also needs copy of your I-20 (front and back), copy of visa. It sure sucks a lot. Not sure if you have tried the employer first for the refund, which would be lot easier.

我几乎都被倒霉的税表整垮了，哪位高人指点一下吧。。。
