both

@Leah M It’s gonna be both and you need to go with him.

please go with him .bring all documents

what did your letter says or states

Most likely it will be a combo interview, especially since the N-400 is already pending. With U.S. Citizenship and Immigration Services, officers usually must approve the I-751 first before approving the N-400, so they often handle both in the same appointment if the files are available. Even if the notice only mentions I-751, you should prepare for both. Bring your spouse and updated joint documents, and be ready for the N-400 civics and eligibility questions. If the N-400 file is not there yet, they may do only the I-751 and schedule the citizenship interview later. - Attorney Ana Gabriela Urizar (All information shared here is for general educational purposes only.
