I just found out today that our tax return (jointly filed w/ my spouse) has been rejected because my wife's (US citizen who sponsored my GC) last name did not much their record. She has changed her last name to mine after we got married but we have reported to everything as far as we know... like SSA, DMV, and everything else. However, it is her first time filing income tax to IRS, could that be the reason why it was rejected? My personal CPA just asked me what her previous last name was and said he will refile.. I'm just worried about when we file our income tax next year, we will face the same problem. I also need to consider the evidence for our documents when I apply for my 10yr GC and USC in the future.
