Many people are suggesting to use 1040NR form to file in F1 status. THIS IS WRONG GUYS. You have to file 1040NREZ whether you are married or single if you are in F1 and present in the US for less than 5 years.

The tax law in the US does not provide any deduction or exemptions for the spouse or dependent child if you are in the F1 visa. Only thing you can itemize as deductions are the taxes (state or anything) that you pay. If you are using cintax, you know what I am talking about. Everybody is single for tax purpose and should use 1040NR-EZ. You will definitely think, it's unfair. Sure; it is but it still is the law of this "great" land.
