Hi,
I am a student on F1 Visa and got married last year (2012) November in India. My wife got her F2 Visa in December but she came to US with me on January this year (2013). I know I can claim a standard deduction and personal exemption for myself and another exemption for my wife but nothing more. Also, I can file only as "Single". Is there any other benefit I am missing? Please let me know. Thanks
