Critical points to read before you book
The CDC changed its dog import rules in 2024. Mexico is classified as HIGH-RISK for dog rabies. Dogs born in Mexico or vaccinated in Mexico face specific documentation requirements before US entry. Check the current CDC Dog Import page at cdc.gov/importation for the latest rules.
Dogs from high-risk countries must arrive at a CDC-designated airport of entry. Not all US airports accept dog imports from high-risk countries. Confirm your arrival airport before booking.
Cats are not subject to CDC dog import restrictions. A healthy, vaccinated cat with a standard health certificate can enter the USA from Mexico without the CDC documentation steps that apply to dogs.
This route is also used by people moving between Mexico and the US for work or study. The rules apply equally regardless of whether you are a US citizen or a Mexican national.

The CDC high-risk country classification for Mexico
Since the CDC updated its dog import rules in 2024, Mexico’s status as a high-risk country has had practical consequences for pet owners crossing the border with dogs.
Dogs from high-risk countries must be microchipped, and their rabies vaccination documentation must meet specific standards. Dogs vaccinated in Mexico by a Mexican vet may need to complete additional verification steps through the CDC process before being cleared for US entry. Dogs that are not compliant may be turned away at the border or held for assessment.
The CDC website (cdc.gov/importation) has the current flowchart showing which documentation path applies to your dog based on vaccination history, origin, and destination state. Hawaii and Guam have additional requirements on top of the federal CDC rules. Start here before calling airlines or vets.
Cats have a much simpler path
US federal law does not restrict cat imports from Mexico. There is no CDC equivalent rule for cats, no required import permit, and no quarantine. A healthy cat with a standard health certificate from a Mexican vet and a current rabies vaccination is typically cleared without issue.
Some individual US states may have their own rules on cat importation, particularly Hawaii. If your destination is Hawaii, check the Hawaii Department of Agriculture (HDOA) requirements, which include a mandatory pre-arrival quarantine programme.
For cats entering any other US state from Mexico, the process is the health certificate, preferably a microchip, and current vaccinations.
FAQ
Common questions about Mexico to United States pet transport
Not necessarily. Dogs from high-risk countries (including Mexico) may be able to enter if vaccinated outside the USA, but specific documentation is required. The CDC’s Dog Import Form process exists for dogs vaccinated abroad in high-risk countries. Check the current requirements at cdc.gov/importation. In some cases, dogs vaccinated in Mexico may need to arrive at a CDC-registered facility for a waiting period. The rules are complex and worth checking carefully before you travel.
Dogs from high-risk countries must arrive at a CDC-designated airport. Not all US airports are on the approved list. When booking, confirm with the CDC and your airline that your chosen arrival airport accepts dog imports from Mexico. Miami, Houston, Los Angeles, New York, and Atlanta are among the airports that typically handle these arrivals.
No. The CDC high-risk country dog import rules do not apply to cats. Cats entering the USA from Mexico need a current health certificate from a Mexican vet and are typically cleared without the additional documentation steps that dogs require. Hawaii is an exception: cats going to Hawaii need the HDOA 5-day or standard quarantine programme.
Yes. The same CDC requirements apply at land border crossings as at airports. For dogs from high-risk countries, the microchip and documentation requirements must be met regardless of whether you cross by air, land, or sea. Many owners driving across the border with pets are surprised that the rules are the same as for air travel.
