That's what I understood. But discussions here confused me a bit.
In my case, I was not able to file I-485 in Oct, because the perm from my new employer was not approved.
Even after waiting for more than a quarter of my life. I decided not to go back to old employer because I left that place for right reasons (career growth). I am not sure if I made the correct decision. If I had gone back, by now, I could have atleast be in TriShanku Swarga .
I will have to make another decision on EB2 or EB3 (hopefully soon.) I want to do that one right.
