Thanks to your response in advance.
I am on H-4 (not expired), and I-485 is pending following the principle
applicant. I have used AP and currently have a job based on EAD. Can I
still extend my H-4 visa (accompanying the extension of H-1b)?
For H-1b holder, can they extend their visa after using AP and H-1b is
approaching the end of 6th year? Can they get another H-1b visa after they
choose to use EAD for a period?
