Re-entry Permit Question

[aurs]

I received my GC last year, recently due to personal reasons I had to come to India in the month of March this year and before comming to India I have applied for a re-entry permit for 1 year as I was not sure of my duration of stay and I received the receipt notice of the re-entry permit before travelling to India. I'm planning to return back to US sometime during august this year, which is around 6 months of stay out of US. My question is can I travel back to US while my re-entry permit application is pending decision from USCIS , also will there be any additional questioning at the POE due to the pending application.

Thanks
