Change visa extension application from regular to Premium

[kirit_raja]

Hello,

My company does not offer attorney service for my visa extension. So I filled for my 8th year visa extension my self in August, 2005. It takes 90 to 150 days for the regular processing. So I requested my employer for premium processing. I have two questions:

1) What is the procedure to convert my visa extension application to a premium processing application?

2) How long does it take to get the visa extension in premium processing?

Thank you very much for all your help.
