Is it possible to file for green card through tps? If yes, how? What are the requirements?

Are you for real? People like you should be Donald Trumped.

I have heard that you can.

If you were never out of status and your employer is ready to file GC, then YES. I got mine. You can be eligable to apply GC while in TPS status. The most important things are as follows:-
1) Never out of status
2) finished school
3) Get job (constultancy in my case)
4) Employer ready to file your GC. Process little lengthy but worth it.
PERM --- I-140---1485 --Time line 1 year - 18 months (Depends upon your employer interest as well as your LUCK)
