H1B Visa extension after 8 years on I-140 revoked after 180 days

[Amit N Sharma]

Hi There, 

I got my H1B visa approved in year 2014 and I-140 in Sep-2016. I changed my employer in Jan 2020 and my previous employer filed an application to revoke my I-140( by this time my I-140 was approved for more than 3 years).  My current Visa is valid till Jan 2023. 

My question is about the next extension. Do i need to get the GC process started by the new employer and have my I-140 re-approved before filing the extension for H1B or my current employer can file my H1B visa extension on my I-140 which was approved for previous employer.

Please advise. 

Thanks

Amit

Current employer can use the previous i140 to apply for an extension
