Pending I-140 and received job offer. Suggestions please

[nikshit1984]

Hi All,
I am currently on H1-B visa and my GC has been initiated with my current employer. I am in a very tricky situation as to whether to switch the current employer or Not.
Below is my situation:
1. H1-B Max out in May 2018.
2. I-140 already filed with current employer and expected to approve in next couple of months.
3. Currently H1B premium processing too is stopped.

I have received a job offer where they are willing to Hire H1. I am in a dilema whether to switch or stay with current employer until I receive my I-140.

any suggestions.

Stick with your job until the I-140 has been pending for 180 days

Thanks for the response.
Does this mean that I wait until my I-140 is filed and completed 6 months or post I-140 approval 6 months.
Another question I have is can I switch immediately post I-140 approval? Will my Old PERM filed earlier be considered while filing extension beyond Max Out with new employer.
