Getting a letter of compliance?

First time posting here, short story my father in law who owned a 996 in Ontario Canada passed away this summer and my mother in-law has asked if my wife and I would like the car (we live in Pennsylvania). After looking at all the info and forms needed to do this I’m stuck at getting a letter of compliance from Porsche. They consider this a cross boarder sale even though the car is staying within the family. Is there any way to get this golden letter or is our Porsche dream dead? Thank you
