I applied for N400 on the grounds of 3 year marriage, the interview was conducted and I was given an RFE to prove marital union. We have a bona fide marriage and had to prove that already to gain LPR, which was granted for 10 years. Without going into the drama, here are the facts. Due to marital issues, I cannot provide all the evidence/documentation requested and since the interview, my spouse has requested a formal separation. I am considering withdrawing my N400 application and reapplying after the 5 year criteria, but have questions: 1. Can I withdraw my application at this stage, after interview and RFE, and if so, do I need to provide a reason? 2. If I withdraw my application at this stage, is there a requirement as to when i can reapply, either under the grounds of marriage or the 5 years? 3. Are there any potential negative issues with withdrawing at this stage on future reapplication, with or without a divorce? 4. Does withdrawing my N400 at this stage affect my LPR? Thanks for your time.
