Once you've applied for a green card and the PERM and I-140 has been approved and your I-485 has been pending for 180 days, you do have portability. You can leave your current employer, but you must find another position that is substantially similar.

Labor certification and I-140 processing used to be painfully slow. I waited 3.5 years just for my labor certification. However, the new PERM process is much quicker, so you'd probably only have to wait 1 or 2 years to be eligible for portability.

You can't file for an i-485 if your date is not current which is the case for folks from India/China. So there is no true portability.
