who knows which companies can do the sponsorship

Hi all,

I'm in SF now and I want to get a job in the United States.
I need the companies which can do the sponsorship for me.
I got MBA degree, major in international business on Dec, 2008 at University of North Alabama.
Moreover, I had three months internship (Nov, 2009-Jan, 2010), as a marketing intern and tradeshow assistant, at the rental housing website company
in SF.
I need your guys help to offer me the information that the companies in the United States can do the sponsorship
I really need this information, and kind of hurry!!!!!

I really appreciate your help!
