I was approved for a change of employment but my previous employer wants to keep me on part time. Can they just amend the existing petition which they havent revoked and file for part time hours? My understanding is that the petition is valid till the expiration date. Right? Otherwise what is the best way to do this?
What type of USA visa are you talking about here?
Is it H1B?
Yes. H1B cap exempt employers both of them.
Multiple h1B jobs at same time with Concurrent H1B. Jobs can be in different fields, specialty occupation. Primary H1B employer not required to be informed.
