she didn't get her citizenship until 2006. if you go to the u.s. customs and immigration service page about how to prepare, u.s. customs and immigration advises you that "your tax returns are very important proof that you are eligible for naturalization" meaning proof that you're eligible for becoming a citizen "on the day of your interview, bring certified tax returns for the last five years or three years if you are married to a u.s. citizen. so when melania trump went for her citizenship interview in 2006 he would have had to bring tax returns, including from this first year when she was married to donald trump and that tax return would be used as a very important piece of evidence as to whether or not she should get citizenship so you better believe the 2005 tax return is going to be sterling, right? that it's going to display excellent citizenship and no red flags whatsoever.
