I had uploaded marriage, divorce certificates, tax returns, birth certificate, LPR copy with the application
Since i did not have proof of ex-spouse’s immigration status i uploaded a letter requesting USCIS to look up status based on Alien number
Officer first placed me under oath. Asked for GC, DL, tax returns. Interview was very simple. Civics questions, reading and writing test. N 400 questions. At the end she gave me a letter and mentioned i was approved and that i will get invitation for oath ceremony.
Overall it was a smooth experience. My advice would be to upload all relevant documents online and take originals to the interview. Best part was that no VAWA questions were asked 😊
