I was on a F-1 Visa and not working for the past three years and married US citizen in August. Got my Green card in December. I am currently finished with school and have no income (unemployed) nor did I for 2013. I have no SSN but was issued some sort of # on a 1098-T tuition statement. How should my wife file her taxes? She supports me as things stand and did throughout 2013. She has always filed as single but how do we file taxes now?
