Last year I finally convinced my employer to do PERM for me.

So, they did the recruitment phase and nobody applied. They haven't filed the application for PERM yet though. It will probably be done this month.

I know after that is 6-8 month wait for the PERM approval.

My question is,
1. What to do after PERM is approved? Employer said I am on my own after that so has anyone done the rest of the steps by hiring their own lawyer?
2. Can I get my green card before Christmas? I want to visit Nepal during Christmas break.
3. I applied for TPS so I have my biometrics done. Will they ask for it again? I will do priority processing and can I skip the biometrics?

Thanks.
