APPLY FOR I129 & I140 TOGETHER

Hi,Actually I had completed 2.5 years of H1b in USA but I moved back to my home country as my extension got denied. I have applied H1b extension again from my home country under cap exempt and also received the receipt number from USICS but its going to take 6-8 months to get the decision from USCIS as premium processing is on hold.

So I have 3 questions-1. Can I apply for I-140 (green card) while H1b extension is in process with USCIS?

  1. Will processing I129 & I140 together affect decision of USCIS either for I129 or I140?3. If my H1b extension(I129) get approved before I-140, Can I go for stamping & travel to USA on H1b ?
