My mom just came back from her naturalization interview about a week ago. She passed the interview but the examiner handed her the N-652 and she told me she was going to send me a letter asking for additional documents about my mom's case. We received the letter and it said that my mom needs to submit her tax returns from her home country. The thing is, we moved here 14 years ago and she has never filed for taxes in home country because she was a housewife. she did visit about 2 times since her Green Card but no more than 6 months at a time. What could this mean? Is the examiner asking for something non-existent because she doesn't want to approve her case? please help!
