Sorry for typing in English.

I'm F1 visa. Last year, I worked for a company located in CA as a contractor, but through two different agents for the payroll, from Feb. 2003 to April 2003, my payroll was from an agent in CA, from April 2003 to July 2003, my payroll was transfered to another agent in GA. Now, I got W-2 forms from both of the agents, what should I do for my state tax return? Should I file tax forms from both states? And what the forms are? Thank you very very much.
