Although the visa policy of the U.S. also applies to the U.S. territories of Guam and the Northern Mariana Islands, both territories have additional visa waiver programs for certain nationalities. The Guam–CNMI Visa Waiver Program, first enacted in October 1988 and periodically amended, permits nationals from 11 countries in Asia, Europe and Oceania to enter Guam and the Northern Mariana Islands as tourists for up to 45 days without the need to obtain a U.S. visa or ESTA. A parole policy also allows nationals of China visa-free access to the Northern Mariana Islands for up to 14 days.
