Coco to Taiwan

I'd like to think I am a reasonable person with an average intelligence level. I even completed college in an top-tier Taiwanese university (although not without hurdles). I somehow even got a Ph.D. at an Ivy League!? So how is it that I can't understand the 'simple' procedure to bring my cat, Coco, back to Taiwan? Coco landed with me today in Taiwan after a month in SF. During that time, I called my vet in New York, set up a new vet in SF, and scheduled appointments with the California USDA. I called the Taiwanese equivalent of USDA (BAPHIQ) several times to confirm that I have everything needed to bring Coco back. And of course I am still 2 criteria short. Even though the form listed the name of the vaccine that Coco received 7 months ago, apparently with all the vet in Taiwan, they don't know which kind of vaccine it is (whether it was an activated or inactivated form of Rabies vaccine), which took me less than 3 minutes to find online. Also, while they accepted my vet's email saying that the vaccine was a booster shot in previous exchanges, since the USDA didn't stamp that letter, it was not good enough. So later tonight, I have to make more phone calls to the US to contact the USDA, my vet and who knows what. ARHHHH!!!
