Every year I file my tax return as MFS because my husband is a foreigner and he does not live in the US.
I also live abroad with him, but I file my tax return as I am a US citizen.
Every year, I make sure to insert his SSN, but I just realized that his SSN states has has a stamp that says "VALID FOR WORK ONLY WITH DHS AUTHORIZATION).
I was wondering if I should have not included his SSN in my tax return in the first place.
Could this cause a problem in the future if we ever move to the US in the future?
