Case sent back to uscis for review after 221g


I applied for H1B in April 2016 and got through the lottery. My petition got approved for 1 year. I went from visa stamping but unfortunately got 221g. The recent update on my case is it has been sent back to uscis for further review.

My question is in this situation, am I eligible for H1 transfer by another employer ?

Please answer urgently.
