First of all , we all sorry to hear about it,
If you planning for FTJ, it is simple and may take upto 6 months,
If u married before your 485 apvl, all u need to file I-824 when u get receipt , send the following Notarized (as many docs u can notarize, if not then use simple copy) docs to consulate (once she is there in home country).
1. Notzd copy of 485 approval.
2. Notzd copy of 824 receipt.
3. Notzd copy of our GC boths side
4. Notzd copy of I-140 apvl.
5. Your marriage Certificate
6. Her Birth Certificate
7. Your all pages of Passport.
8. A seperate sheet of her info (name addr ph, email etc at home country)
Once they receive they would initiate FTJ case for her. and will contact to her at her home country. later they will send forms to fill it out and they would ask to send supporting docs, like I-134, medical, police report, filled form DS230, some org docs etc.
