My mom was denied entry into Taiwan today due to her US passport expiring in less than 6 months (literally 5 months and 2 weeks.) She was leaving from Honolulu on China Airlines, and the manager claimed that they got fined repeatedly by the Taiwanese government and refused to let her on. I was wondering if anyone was able to enter Taiwan with a US passport that was less than 6 months, and if so, how would one go about doing that? It seemed the manager of CI was being extremely strict, but it doesn't seem like that big of a deal since on the same trip she got a visa from the Mainland Chinese embassy which also requires a 6 month expiration as well. When she got the visa for China, they let her slide.

Thanks in advance for any prior experiences dealing with entry into Taiwan.
