Hi. I was in United States during 2011 on L1 Visa and came back to home in August 2011. I missed to get her ITIN or SSN during our stay. Now when I file my IRS returns as "Married-Filing Jointly", it ask for SSN of my wife. Is there any way to get it filed jointly? Or any other forms to be submitted to prove my wife stay in US during 2011?
Thanks in advance.
Kamalesh.
