1. Many countries require a passport to be valid for six months. Sometimes these six months are counted from the date of departure, or from the date of entrance. Even though some of these countries only legally allow you to stay for 30 days or three months.. Yes, but it's not NZ insisting that our passports be valid for 6 months more, it's the countries we're visiting. NZ requires visiting people to have 1 month free after the tourist visa expires. It differs from country to country.
A passport's validity is generally determined by the applicant's age. In the US, passports issued for adults ages 16 and older are valid for 10 years. Children 15 years of age and under receive passports valid for 5 years. There are two primary exceptions to this rule: a second passport is valid for 2 years and an emergency passport is valid for 1 year. In some instances, when replacing a lost passport, for example, the Department of State may issue a passport with lesser validity (usually 1 or 2 years).
