-Just do H1 transfer like ordinary H1. The problem is if your I-140 was sponsored by your current employer such as based on PERM, you can not use this approved I-140 to file I-485 if you change the employer unless you will come back to work for this employer. Also, the employer can withdraw the approved I-140 anytime so that you can not use this I-140 to extend your H1 anymore unless you file a new I-140 and get it approved.
若是新的,是否還會有六年?多謝了!
-You only can transfer/extend the H1, and you are not qualified for a new h1 for another 6 years.
