Mom was interviewed on Dec. 06, 2018 at the US Embassy Kingston Jamaica.
I can't remember everything that was asked but some of her questions were:
What is your petitioner's name?
What is your petitioner's address?
Where does she (petitioner) work? My mom said she was asked this question at least twice. Of course, because I do not make enough money.
Where did she (petitioner) got married?
A few other easy questions about the petitioner that I can't remember.
She was handed form 221 (g) to submit a qualified joint sponsor
2017 W2
2017 tax return
Proof of status from joint sponsor
Consulate / USCIS Member Review #25659
