Entry requirements for Guam are the same as for any U.S. destination. Although U.S. citizens are required to possess a U.S. passport, on a case-by-case basis, photo I.D. and proof of citizenship may be accepted. In general, citizens of most other countries must have a valid passport with a U.S. visa.
In October 1988, the U.S. federal government implemented the Guam-only visa waiver program. Citizens of more than a dozen countries were granted permission to enter Guam without a visa for a period of up to 15 days. Travel onward to other U.S. ports was not allowed. Passengers were required to arrive on a signatory carrier.
On November 28, 2009, the visa-waiver program for Guam and the Commonwealth Northern Marianas Islands changed. The period of admission was extended from 15 to 45 days. The visa waiver, however, still does not allow visitors to travel onward to other U.S. ports. Arrival on a signatory carrier is still required.
Under the new program, holders of passports from Australia, Brunei, Hong Kong, Japan, Malaysia, Nauru, New Zealand, Papua New Guinea, the Republic of Korea, Singapore, Taiwan and the United Kingdom are required to complete and sign Form I-736, Guam-CNMI Visa Waiver Information form, and a completed Form I-94, Arrival-Departure Record. A valid unexpired ICAO compliant, machine-readable passport and a clean record of any prior admissions to the United States is also required.
The Hong Kong Special Administrative Region passport and Hong Kong identification card is required for admission. Citizens of Hong Kong were previously eligible for admission under the Guam visa-waiver program as citizens of the United Kingdom.
The following four countries were removed from the list of those visa-waiver participating countries as of November 28, 2009, according to the U.S. Department of Homeland Security.
- Indonesia, Vanuatu and Western Samoa because of high visa refusal rates.
- The Solomon Islands because of ongoing political and civil instability.
Due to the frequent U.S. Department of Homeland Security regulations, please refer all the visa-related information to the U.S. Department of State website:
