NO, the Interstate Commerce Permit is in effect a Tax imposed by Congress way back and administered by the USFWS. It is tedious, an imposing stack of forms, much of which does not apply. Many breeders/sellers, and certainly me, are happy to assist you as we have been through the process before. It asks you to provide evidence you have applicable experience and know the basics of Dryamarchon care, and have adequate facility, etc. Not hard, but some answers you should consult with experienced breeder/seller prior to submitting.
Some States may have their own permits, and that is different and I am not addressing those at this time. Eastern Indigos require more effort than some to acquire, but I think worth it when you jump the hurdles...
Sometimes the first time is intimidating, but you will find it is not hard. You can do it, many have gone before you!
good luck, Vic
