I have already used up 6 years and extended my H1B based on approved 140.
AC 21 says that you can no longer extend more than 6 years if your PD is current for at least one year and you didn’t file AOS.
The problem here is, if I change an employer, I have to file PERM and 140 again. At the same time, I cannot file AOS even though my PD from old I140 is current. Will this trigger the rule mentioned above so that my future H1B extension will be denied because I fail to file AOS within one year of visa availability?
This feel so unreasonable since PERM by new employer can take long time.
Thought about filing PERM immediately after I start from new employer and also DIY a national Interest waiver 140 at the same time.
