L1B Individual went RFE

[Bala Thangaraj]

Greetings!

My L1b individual was under premium processing and i got RFE yesterday, it says they have sent an email via snail mail does anyone know how long will the entire process will take from now? My existing L1b was canceled without prejudice last month, i've my car, apartment and other stuff back in united states. I'm worried now. . . any advise would be helpful.

Thanks,
Bala
