Hi,
My situation is like this:
I was on OPT (F1) status till October 1, 2009 and was exempt from FICA taxes from Jan 1 to September 30th last year. I got married in October and filed 1040 NR and got Std deduction for me and my wife as per article 21 for Indian students. Now, I want to file an amended return with 1st year choice and file a joint return with my wife since I passed the SPT in June. The pros being I will be able to get make work pay credit and married filing jointly refund, however I am concerned if IRS will ask me to pay FICA taxes for my F1 period as I am filing as resident. Please advise if I file as resident now , am I supposed to pay FICA taxes during my exempt period. Also my wife has ITIN no, is she eligible for make work pay credit while filing a joint return or not?
