How long do i need on my passport to travel to portugal?
There are no limits on a fresh passport; you may use it from the first day of its validation. There are however some limits on the duration of the passport. You may for example not travel to certain Asian countries if your passport is not valid at least six months beyond your planned stay. European Union countries do not require this validation from a U.S. passport holder. You may enter the country with a valid passport on arrival. Since the U.S. government also requires a valid passport to enter you may stay in Portugal as long as your passport is valid to get back home, however not to exceed 90 days in a 6 months period as tourist or for business without a visa..
