Hi Ron, I have an approved I-140 from my current employer. I am in 9th year of my H1B and got couple of extensions already after completing 6 years on my H1b. But the category I am in right now is EB3. My priority date is Feb 2011. I am actually working full time and happy with the job, just that it is hard to get EB2 porting done with the same employer. So I found another company which is ready to start my GC in EB2 (as a future employee). So my plan is to ask them to apply for PERM and I-140. Only when Eb2 moves to Feb 2011, I plan to join that company and apply for I-485. Here is the question I have : is there a time limit for applying I-140 after PERM is approved? Or can we wait for applying I-140 after PERM approval (lets say couple of years)? I need to know this to decide when to start the processing. Please let me know. Thanks.
