I filed I751 March 2021, and then my N-400 January 2022 and had my interview today. I got a phone call yesterday afternoon advising to bring my spouse to the N-400 interview, they would be combining my I-751 and N-400 interviews. I passed the interview and the immigration officer stated they will first clear my I-751 today and then approved my N-400 tomorrow after the I-751 has cleared from the system. The phone call yesterday was a slight curve ball, luckily my wife is self employed and could make the interview. I know this thread relates to I-751, but just a heads up if any of you have filed an N-400. I’m just glad it’s over, I’m so tired of visiting the DMV to renew my license. All the best to you all.
