Do I need a visa to visit Taiwan if I'm a US citizen?
No. Also unlike other places, Taiwan won’t impose a six month rule for passport validity (i.e. you don’t have to have six months before your passport expires).The only situation where you’d need a visa is if you are interested in setting up a Taiwan bank account, in which case you’d need a visa to get the ID, to get the bank account.You might want to consider getting a Taiwan bank account if you are an active trader of bitcoin, since getting a Taiwan bank account lets you transfer money out of Bitfinex.
