I need a copy of my W-2 forms for 2007 I received from unemployment. How do I go about obtaining a copy?

Best method is to contact the employer or issuer. For more alternatives, read Your U.S. Tax Return: How to Get Missing Forms W-2 and 1099

Actually, the form will be a 1099-G.

You can get copies from the state Department of Labor, probably on-line.
