Regarding H1b-transfer while on AP

USA H1B Visa
1

Hi Sourabh and other experts,

I had attend H1b interview 2 months ago and unfortunately received a white slip with AP marked on it and no other documents were requested and so far, there is no progress on my case. My H1b petition is set to expire in coming Feb. I have the following questions on this regard:

  1. If I don’t get the approval before Feb and if the petition gets expired, can I still use this approved petition for a cap exempted transfer if I get an opportunity from another employer?

  2. I have a potential sponsor ready to transfer my H1b and I think they would back out if they come to know about my AP status. Can I go ahead and claim that I have not appeared for any stamping, so far? Is there a way the new employer can check the current status of my H1b?

Thanks
