what is RFC....

Got my receipt number… i have been following this site and read somewhere about RFC… what is RFC?

Also is there an option to upgrade from regular processing to premium processing after receiving the case number?

Not RFC , RFE… k

Yes you can upgrade your application from RP to PP, but there is no point in doing it once you get through the lottery. In case of NEW applications, many people opt for PP just to know the results sooner and then to get on with Plan B in case of rejection.

Thank you for the response. I did figure out later that there is no point in going for PP.

Do you happen know what is RFE?
