Advise. No reply to 221g query and H1B petition expired. Is it cap exempt ?

Hello,

Can someone please guide on the below query

My H1B petition was approved for only 1 year from Jan 2016 - Jan 2017.

I received 221g query during visa interview in June 2016(white slip requesting project documents).

My employer replied with the documents in Dec 2016 and haven’t received any response yet.

Also, my petition has expired now.

What can be done further ? Can another employer file a cap-exempt petition for me ? If I am cap exempt, then for how many years ?

Please help!

Thanks in advance!
