I have been in permanent resident for over 5 years. So according to the paperwork I do not have to file based on marriage to a US Citizen. I originally came up on a K1 VISA. My questions is if I have to bring tax refunds , 3 years ago i filed as married filling jointly. These past 2 years I have filed as Head of Household with one of my daughters, as my wife owes money. She files for the other kid separately. Will this be a problem?
