I am a LPR with a 2yr resident card based on marriage, it expired on 2021 and I have jointly filled for i751 ROC 3 months before expiration. I filed for Citizenship based on 3-year marriage, the 4th year of residence and marriage, NOT the year after filling for ROC, financial constraints is the reason, ROC was still pending at that time. I've recently got the notices to attend to the interview for both i751 + N400 (combo), one ask me to attend by myself and the other me ask for me and my spouse. Just with 2-3 weeks left before the interview my USC spouse wants a divorce and do not want to cooperate to come to the interview with me. I have research enough to know and understand that N400 is considered invalid/denied at this point and very likely will raise question if I file again. Divorce hasn't been started or summitted yet. What are my next steps? with the interview already scheduled, is it possible to withdraw the N400 at this stage? where do I file such withdrawal?
About the i751 interview, I think I've read that I should change it to a divorce waiver even if the divorce is not final, is it best done at the interview or before? and how such waiver is done? re-filling another i751 and bringing copies again of its evidence + new evidence.
Misc.
Reason of divorce is not unfaithfulness and marriage was entered in good faith.
