Apply for h4 when H1b- 221G is pending

Hi Anil, I went to H1b stamping in Mar. I got 221g blue slip. I have responded back to it as requested by consulate. Due to travel ban, the case is pending. I’m still waiting for the result in India. In this situation, can I apply for H4? Will there be any challenge?

It depends on what was the form 221g issued for.

You can apply H4. But, if form 221g is for any personal level issue, then it will be issued again.
