UM is one of those destinations that starts with 'where?' and ends with a CDC checklist. I keep a spreadsheet just for the high-risk-country flag, because it decides whether Luna sails through or spends 28 nights at a designated facility. This trip's answer changes depending on where the flight departs — so the very first cell in the sheet is 'origin risk status.'

Bringing a pet to United States Minor Outlying Islands requires three documents in the right order: a microchip, a rabies vaccine within the destination's wait window, and a government-endorsed health certificate. The table below lays out exactly what's required, what's not, and where each rule comes from.

Timing chain

Day -90 microchip implant · Day -84 rabies vaccine deadline · Day 0 arrive at customs

The chip must be implanted before the rabies vaccine — never the same day, never after. A vaccine dose recorded before the microchip's ISO number is on file gets rejected by CDC on arrival, forcing a fresh vaccination and a new wait window. Book the chip appointment two weeks ahead of the rabies visit so both dates sit cleanly on the CDC Dog Import Form.
Quarantine on arrival runs 28 days at a CDC-designated animal care facility when the dog is coming from a rabies high-risk country and has not met the alternative approved-vet pathway. That means 28 nights away from the owner, with facility fees paid up front. Confirm the origin country's risk status before booking so the itinerary matches the paperwork that clears at the port of entry.

Frequently asked

Does my pet need a microchip for United States Minor Outlying Islands?
Yes. United States Minor Outlying Islands requires an ISO-standard microchip, and it must be fitted before the rabies vaccination to be valid.
How long before travel must the rabies vaccine be given for United States Minor Outlying Islands?
The rabies vaccine must take effect at least 84 days before entry, and can be given from 12 weeks of age. Travelling before that window makes the vaccination invalid at the border.
What if my flight is delayed past my health certificate validity?
If the certificate window expires before you board, you'll need a re-issue. Build a 1-2 day buffer between the cert date and departure to absorb minor delays.
What happens if I forget a document?
At the destination airport: at best, an extended inspection while you produce backup; at worst, the pet is held in quarantine or returned to origin at your cost. Bring printed copies.
Budget for 28 nights of CDC-facility boarding on top of the ticket — daily rates and reservation deposits vary by facility, so quotes must come from the CDC-designated center that will actually hold the dog. Book the quarantine slot before the flight and match the arrival date exactly; an unbooked arrival is refused entry and returned on the next available carrier.
UM articles get long because the routing map does — Wake, Midway, Palmyra, Johnston all bring their own CDC operator relationships. The plan changes when the departure country changes, so building it once and rechecking the risk status the week of departure is the only real workflow. Pawgo's personalized plan pulls in the current CDC status and keeps the sheet honest.
