Yep as Cyclic Hotline says, the L1 visa is for intercompany transfers.
As a director of a UK software house, this is the Visa I received when I moved to the States to open a US branch of my company.
It took nearly 7 months to come through, which is longer than normal - I believe that they are currently taking approx 6-8 weeks.
You can find out more at the INS website.
