Bit of a leap of faith, innit? Do you consider insurance companies trustworthy in general? Do you have faith in a Taiwanese contract? Put the two together…
By the time you get back to the States the government here will have taken time out of his busy day to pass a law saying foreigners can’t do whatever it is you want to do. Seriously. Can use ATM cards overseas. Can’t use ATM cards overseas. Can have a credit card. Can’t have a credit card. Driving licence valid for 6 years. Driving licence not valid for six years. And so on.
I presume this is in the wife’s name? If it is then I reckon it might be OK. Personally, I wouldn’t trust any insurance company as far as I could throw it, and a Taiwanese one… well… never sign a contract you can’t litigate.
