Contact cryonics companies. If someone is familiar with the process of organizing cryopreservation of foreign citizens, it must be them. I'm aware of 3 cryonics companies worldwide:
Alcor, Cryonics Institute (USA), KrioRus (Russia)
KrioRus's prices should be the most affordable: 12000$ for neuro. Despite situated in Russia, somewhat isolated country, I remember I heard that they did cryopreserve foreign citizen. Get informed and prepared beforehand, and good luck.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
