My husband and I attended his ROC (I751) interview on March 14, 2023. We filed the paperwork back in June 2020, so we’ve waited a long time for the interview. We brought lots of evidence, such as title to car, deed to house, bank statements, utility bills, tax returns for the last 6 years and more. We both thought the interview went well and she (the USCIS) took 3-4 statements of every file we brought with us. She asked my husband my birthday and asked me our marriage date. Last Saturday, we received an I-797C, Notice of Action. The letter stated: This is to advise you that, due to unforeseen circumstances, we have canceled the previously scheduled interview on Tuesday, March 14, 2023 at 7:30 for the above applicant. We regret any inconvenience this may cause. You will be notified of any further action taken on this case, including any rescheduled interview information, under separate notice. The notice date was March 14, 2023 which was the date we went to the interview. We have heard nothing else. Is there advice anyone can offer? Thanks for reading and for any help you can give us. We will have been married for 6 years in May and have waited so long for this to be over.
