It is not hard at all to get the C.I.T.E.S documents but it takes time. Usually 4-6 weeks. If I remember correctly you can have them expedited but it cost over double the normal document price.
:I am getting a friend to bring across the border CITES II torts, crocs & other herps. How difficult is it to get the permits from the US? I have read R. Stockwell's, USF&W, & CITES websites about process, but I would like some practical experience/advice.
