Currently on my H-1B post 6-year based on approval of PERM and I 140 under EB - 2. Would be In the process of switching jobs for some personal / professional reasons very soon.<br>

1) What documents would I need to have with myself - corresponding to PERM and I-140 - so that I can retain my priority date and start another green card process with a potential new employer ?
<br>
2) For the documents above - would I need to have the originals or the photocopies ?

I had applied for H-1B extension on May 15, 2015 with I-94 card expiring on Aug 29,2015. Due to some emergency, I traveled to India in June and returned in July with new I-94 card expiring on Nov 2015. Now, it's been 6 months that I applied for extension, no response from USCIS. Will there be any problem since I filed my H-1B extension with old I-94. Do we need to amend my case with new I-94 card?

I have a question on EAD validity for the below scenario. <p>
H-1B holder got I140 with Employer A and applied EAD for H-4. H-4 is valid until MM-DD-YYYY 10-29-2018. Now H-1B holder moved to Another Employer B, then at this point he doesn't have Approved I-140. Will EAD which received using Employer A valid until MM-DD-YYYY 10-29-2018? I knew for renewal of current EAD after 10-29-2018, we need approved I-140, but not sure exiting EAD is valid until 10-29-2018 if H-1B holder moved to Employer B.
