Permits are handled by the USDA/aphis. You can e-file for permits online at
http://www.aphis.usda.gov/ or by fax or mail to :
USDA/APHIS/PPQ
4700 River Road
Riverdale, MD 20737
301-734-5302 Office
301-734-8700 Fax
If you have a local USDA office, you would need to go in and show them a picture ID (after setting up a provisional account online) to be able to file your permits online.
Hope that helps,
