Employer for get to file H4 for wife

[ranurandhawa]

I am in USA on H1B. My visa is expiring on September 11,2011 but I just got my first extension. So I can stay here until 2014.

My wife is on H4 visa. And my vendor is applying for her H1B (Premium processing).

By mistake, my employer forget to put her H4 extension (I just got my h1b extension)

My Question is:

Can my employer able to put her h4 extension now?

Is there any premium processing thing for H4?

Or

Can my vendor just file for her H1b in premium processing? And there is no need for H4 extension?

Please suggest,

I just got 1 month to take action?

I appreciate your prompt response.
