Yes, U.S. citizens can live in Guam. Because Guam is an unincorporated U.S. territory, moving there works the same way legally as moving between states: no visa, no permit, no employment authorization, no paperwork beyond what you’d need for a domestic move. The catches are political and practical, not legal. You lose your vote for president, you file income taxes with the Guam government instead of the IRS, and a few federal benefits stop at the territory’s edge.
No Visa or Permit Required
Guam is governed under the Organic Act of Guam, which Congress enacted in 1950 and which today makes anyone born on the island a U.S. citizen at birth.1Office of the Law Revision Counsel. 48 USC 1421a – Unincorporated Territory; Capital; Powers of Government2U.S. Department of State Foreign Affairs Manual. 8 FAM 302.3 – Acquisition by Birth in Guam For anyone already a U.S. citizen on the mainland, Guam sits inside the U.S. domestic travel area. You can fly there without a passport, though airlines expect a government-issued photo ID at the gate. Once you land, you can rent, work, and settle in without asking anyone’s permission.
What You Give Up Politically
Moving to Guam costs you your vote for president and vice president. Under Article II of the Constitution, presidential electors are apportioned to states, and the 23rd Amendment extended that right only to the District of Columbia. Guam is neither, so its residents have no electoral votes. The island runs a nonbinding presidential preference poll every four years, but it carries no legal weight.
In Congress, Guam has one non-voting delegate in the House. That delegate can serve on committees, introduce bills, and speak on the floor, but cannot vote on final passage. There is no Senate representation. You keep full participation in local government: races for governor, the 15-member unicameral Legislature of Guam (all senators elected at-large to two-year terms), and local referenda.3Guam Election Commission.

For many people, giving up a presidential vote is an abstraction. For others, it’s the reason not to go. Know which one you are before you commit.
How Your Taxes Change
Guam runs a “mirror code” income tax. Federal law requires that U.S. income tax rules apply on the island, but the tax is payable to the Guam government, not the IRS.4Office of the Law Revision Counsel. 48 USC 1421i – Income Tax In practice, Guam uses the Internal Revenue Code with “Guam” swapped in for “United States” and “Governor” for “Secretary of the Treasury.” Rates, brackets, deductions, and credits are the same. The check goes to a different treasury.
If you qualify as a bona fide resident of Guam for the entire tax year, you file with the Guam Department of Revenue and Taxation and report your worldwide income there. Filing and paying in Guam relieves you of any obligation to file with or pay the IRS.5eCFR. 26 CFR 1.935-1 – Coordination of Individual Income Taxes Bona fide residency generally rests on three tests: a presence test (enough time on the island), a tax home test (your primary place of business is in Guam), and a closer connection test (your stronger personal and economic ties are to Guam).6Internal Revenue Service. Publication 570 – Tax Guide for Individuals With Income From U.S. Possessions Military personnel stationed in Guam follow separate rules and generally do not qualify as bona fide residents based on their assignment alone.
One boundary worth noting: the Guam legislature has statutory authority to add a surtax of up to 10 percent on top of the mirrored income tax, though the file indicates this power has historically been used sparingly.4Office of the Law Revision Counsel. 48 USC 1421i – Income Tax
Which Federal Benefits Follow You
The answer is program by program, and the gaps matter.
Medicare
Medicare’s coverage definition of the “United States” explicitly includes Guam.7Medicare. Medicare Coverage Outside the United States Part A and Part B coverage continue on the island. The practical limit is the provider network: fewer Medicare-accepting providers than the mainland, and some specialty care may require travel to Hawaii or elsewhere.
Social Security Retirement and Disability
Regular Social Security retirement and disability benefits continue without interruption. The Social Security Administration treats Guam as part of the United States for benefit payments.
Supplemental Security Income
SSI is the critical exception. The federal cash assistance program for low-income seniors and people with disabilities does not extend to Guam or any other U.S. territory. Congress excluded the territories when it created SSI in 1972, and in United States v. Vaello Madero (2022) the Supreme Court upheld that exclusion, holding that Congress may treat territories differently from states in benefit programs where there’s a rational basis.8Social Security Administration. Supplemental Security Income and United States Territories If you receive SSI now and move to Guam, your benefits stop. Legislation to change this has been introduced but, as of 2026, has not passed.
Becoming an Official Resident
You can live in Guam the day you land, but a few steps make you an official resident for local purposes.
Driver’s License Within 30 Days
New residents must obtain a Guam driver’s license within 30 days of arrival.9Government of Guam. Guam Driver’s License and Identification Card Application Bring one identity document (a U.S. passport or birth certificate), proof of your Social Security number, and two documents showing your Guam address, such as a utility bill and a lease. Setting up utilities and signing a lease early gets you the address proofs in time.
Voter Registration
To register for local elections, you must be a U.S. citizen, at least 18 by election day, and a Guam resident for at least 30 days. Guam law defines residency as living on the island, maintaining a home there, and intending to return whenever you leave.10Guam Election Commission. Registering to Vote Paying Guam income taxes also counts as evidence of residency.
What to Plan for Before You Move
The legal side is easy. The logistics take real planning.
Cost of Living
Nearly everything costs more in Guam than on the mainland. The island imports most of its consumer goods, and shipping costs are baked into groceries, clothing, building materials, and household items. Electricity runs above the national average, with a fuel surcharge tied to imported petroleum. Housing demand is shaped by the large U.S. military presence and tourism. Budget for meaningfully higher day-to-day expenses.
Pet Quarantine
Bringing a dog or cat requires advance work. Every animal needs an entry permit from the Customs and Quarantine Agency, and arriving without one can trigger fines up to $1,000.11Customs and Quarantine Agency. Pet Import Requirements The default quarantine is 120 days at a commercial facility. Pets from the mainland with a qualifying rabies antibody titer of 1.0 IU or higher can cut commercial quarantine to five days or fewer, with the balance of the 120 days served as home quarantine. Titers between 0.5 and 0.99 IU qualify for a calculated commercial stay based on when blood work was completed. Any missing paperwork sends your pet back to the full 120 days, so start months before the move.
Professional Licensing
Mainland professional licenses generally do not transfer automatically. Nurses, doctors, teachers, and other licensed professionals apply for Guam-specific credentials through the relevant territorial board. Nursing endorsement applications, for example, run through an online portal and typically take four to eight weeks with complete documentation.12Guam Board of Nurse Examiners. FAQs Other professions follow separate processes. If your income depends on a license, verify Guam’s requirements and timeline before setting a start date.
Healthcare Capacity
Guam has a hospital and clinics, but the healthcare infrastructure is more limited than most mainland residents are used to. Specialty care often requires medical travel to Hawaii or elsewhere. Guam’s Medicaid program operates under a federal funding cap rather than the open-ended state matching formula, and federal policy shifts could tighten local resources further. If you have ongoing medical needs, identify specific providers and specialists before committing.
