My H1B extesion filed and I have received REF(Request for Evidence)

My H1B pettition was expired on feb-28 and my company has filled the H1B extension. Now I have received REF(Request for Evidence). Any idea how long will it take?

I have a plan to visit India… Can I visit India even when my RFE is under progress??

Your employer gets around 60 days to respond to the RFE. Once responded, USCIS will take 2-4 months to process the response and issue the final judgment.

If you leave US now, your H-1 will continue to be processed, but you cannot return to US until the petition gets approved. You will also have to appear for visa stamping if your current visa stamp has expired; and this in turn will require the extension petition to be approved first.
