My H1B extension is in progress (not on premium). Can I travel to India and get H4 stamped based on my spouse H1B and travel back on H4? I know the COS application will be abandoned when going out of country but is it applicable to extension application also? (I am trying to avoid illegal stay) . Additionally, what will happen if I come back on H4 and my H1B extension gets approved after that.
Thanks in advance
