The Passport

I thought my passport was totally okay, but the people of the Customs, both in Taiwan and in the US,  stopped me to examine my passport. Because there were some wrinkles on it, they thought it was fake and kept asking if I was the person in the picture. They asked me to offer another ID. The Taiwanese Customs never heard of UW-Madison, so they didn't find my student ID useful. Eventually they let me pass but it was very annoying. Well, what should I do?
