AOS In Progress and Is it Possible to Stamp and Travel using H1B

[Chennaistar80]

Frds - I applied for AOS with PD as Jan 17, 2017 and as-is status - EAD and AP Approved (I-140 and I-485 is pending). My H1B visa expires on Sep 15, 2017 and I have an H1B Extension petition approved (not stamped) valid till Aug 15, 2019. I have plans to travel to my Country in September and my question is

Should i travel with a Travel document - AP (I-131)
(or)
Can i go for stamping with my Approved H1B Extension petition (Dropbox) and enter US through H1B Visa

I'm reading/hearing that if i enter through AP (I-131) my H1B status will be Void which i don't want to happen. At the sametime if i use my H1B then my AOS will be void - Which ones are true? Please advice.

I have an Infopass scheduled for Jul 27th to check on this and also check my status on AOS (including I-140)

If you enter using AP, you are no longer on H1, but entering on H1 does not void AOS.

Thanks for the response @scientist2016. My H1B Extension is approved and i have the approved petition with me, but need stamping (Dropbox) as my existing Visa is expiring on Sep 15th. With AOS inprogress can i still move forward with Stamping process (Dropbox).
