To submit EE while in USA or India?

Hi all,
I am currently in USA (physically) on H1B, but may have to move to India temporarily for a few months.
I am working towards gathering all the required documents to fill up my EE profile, which I am hoping to do by next month.

The question is, does it make a difference (in processing times, receiving COPR, etc.) if I submit the profile while I am physically in USA or if I am in India?
Pls advise.
