We just got a letter from USCIS titled "Courtesy Notice of Marital Bona Fides" and it's basically asking to submit evidence that we are still in a continued marital union for his I-751. Its asking for us to mail in.
tax transcripts
lease/mortgage
bills with both our names
letters from our employers
joint accounts
but we already submitted that in is I-751 application last year. We filled out an N-400 application earlier this year with all that updated info, why would they need it again. Should I try to contact USCIS? Im guessing that agent doesn't have our N-400 info.
