-Either one is OK, but he had better renew the H1 for another 3 years beyond the 6 year limit (If PD become current when USCIS makes decision on the h1, the h1 may be approved for only one year). Of course, he also can renew the EAD and use it to work without renewing the H1.
Please give me advices.
Thanks very much.
Looking forward to hearing from you.
