I am now in the process of filing H1B extension with my current employer (I already used AC21 once). Current employer also did H1B transfer. Based on my green card processing I should get 3 years extension (140 approved & 485 pending for more than 18 months).
Can I change the employer and ask new employer to file H1B extension? Also, Can I file AC21 again? Is there any regulation on filing AC21 multiple times. I also want to have H1B extension as backup.
