I am a LPR and my wife is on student visa. I filed I-130/I-485 together on August 6th. She had her biometrics appointment today (8/29). We got an RFE that has me worried. USCIS is asking for proof of citizenship of the spouse(me). On the I-485 form, she selected option 'a' on Part 2 as the reason for filing I-485. What did you guys choose? Should it have been "h" (other) instead? Please share your experience.
