Hello Fam, I am asking this question on behalf of a friend. He has been married to his US Citizen wife for 10 years but they stopped living together since about 7 years ago. They never got divorced. He applied for his citizenship based on the 5 year rule, he was approved but at the point of oath ceremony his case stalled since 2 years ago. USCIS has now sent a letter now stating that records showed that he and his wife have not been living together and that their “marriage does not appear legitimate”. Coupled with this, they wrote that he has outstanding or overdue taxes.
Please how do you advise for him to proceed? He has 15 days to respond?
