We applied for H1B, H4 Extension and H4-EAD at the same time (second week of June 2021)
H1B, H4 and H4-EAD are still pending. Series is WAC212.
Is it possible to travel to India in December for stamping(assuming I’ll receive H1B approval by that time) and return only when H4 EAD is approved? Will that cause any problems to the H4 EAD application ?
Generally the extension of status application is not abandoned like the COS if the applicant travels outside of the US however it may get denied if the applicant is out of country at the time of adjudication. If that happens, the H4 EAD will also get impacted too and may be denied.
Consult your immigration attorney to discuss your travel plan and follow their advice.
