H1B and i94 expired in Sep/17, filed for extension no response yet. Am I legally in US?

I did my Masters and worked on OPT for year and then my initial H1B was until Sep/2017 and it got expired along with i94. My previous employer was supposed to file for extension before it got expired but he didn’t till the very end. So I found another employer who filed for new extension/trasnfer on October 4th. The case is showing as received since then.

  1. Am I legally here in US?

  2. What are my options if it gets denied now?

  3. Can I join CPT now? I don’t have any documents with except for received receipt.

Someone please help. I am very confused and depressed.

Are you currently working for the old employer or new employer or neither?

Hi,

I am currently working for new employer with a new client.
