I'm not sure if this is the right forum and I haven't been able to find a concrete answer elsewhere. So I know people file the N400 while their I751 is pending, however my wife's GC doesn't expire until 06/2024, meaning we couldn't file the I751 until 03/2024. However, She came on a K1 visa on 09/16/2020 and we got married on 09/17/2020. Wouldn't that mean she could file for the N400 after her 3 years of being here, since our 3 years would be 09/17/2023, and you could apply 90 days earlier (which would be in a few days from now)? If so, is it allowed to file for the N400 before filing the I751?
