Importing Your Pet to Northern Mariana Islands: A Veterinarian's Guide

I've been reviewing pet import paperwork for years, and I can tell you: Northern Mariana Islands welcomes cats and dogs as personal pets, but the documentation must be perfect. I've seen rejections happen at the last minute because owners missed one detail. This guide walks you through every step, every deadline, and every document you'll need—so your pet arrives without delays.

I'm writing this as both a vet and a pet parent. My Cavalier King Charles Spaniel, Pixel (7kg), has traveled internationally, and I know firsthand how stressful it is when paperwork goes wrong. Let's make sure yours doesn't.

Quick Overview: What Northern Mariana Islands Requires

  • Cats: Allowed as personal pets ✓
  • Dogs: Allowed as personal pets ✓
  • Microchip: ISO 11784/11785 (15-digit) — mandatory
  • Rabies vaccination: Required and must be current

Your Preparation Timeline

6 Months Before Departure

Schedule a pre-travel vet consultation. Your vet needs to assess your pet's overall health and confirm vaccination status. This is when you'll discuss the microchip requirement and any health concerns that might affect travel. I always tell my clients: start early. If your pet needs dental work or other procedures, do it now—not two weeks before departure.

5 Months Before Departure

Microchip your pet if not already done. The microchip must be ISO 11784/11785 standard (15-digit). This must happen before your pet's rabies vaccination. If your pet already has a non-ISO chip, you'll need to provide your own compatible scanner—but I recommend getting the ISO standard chip instead. It's the universal standard and avoids complications.

4–5 Months Before Departure

Administer the rabies vaccination. Your pet must be at least 12 weeks (3 months) old at the time of vaccination. The vaccine must be current and administered by a licensed veterinarian. After vaccination, there's a mandatory 21-day waiting period before your pet can travel. Mark this date on your calendar—it's non-negotiable.

3 Months Before Departure

Apply for the import permit. Northern Mariana Islands requires an import permit. The typical lead time is 30 days, so apply now. Contact the Northern Mariana Islands government veterinary authority to request the permit application. You'll need your pet's microchip number, vaccination records, and basic information. Keep the permit number and expected approval date.

2 Weeks Before Departure

Schedule your health certificate exam. The health certificate must be issued by a licensed veterinarian within 10 days of travel. I recommend scheduling this 2 weeks ahead to ensure your vet has availability. The certificate confirms your pet is healthy and fit to travel.

10 Days Before Departure

Obtain the health certificate and arrange government endorsement. Your vet issues the health certificate after the exam. The certificate must then be endorsed by your country's government veterinary authority (e.g., USDA APHIS if you're in the United States). This endorsement is a separate step and takes additional time. In the US, APHIS endorsement typically takes 3–5 business days. Don't wait until the last minute.

5–7 Days Before Departure

Confirm all documents are in order. Gather your health certificate (original, government-endorsed), import permit, microchip documentation, and vaccination records. Verify the health certificate validity—it's only valid for 10 days from issue date. Make copies of everything and keep them in a separate folder. I tell my clients to photograph every document as a backup.

Day of Travel

Bring originals and copies to the airport. Present your health certificate and import permit at check-in. Keep vaccination records and microchip documentation with you (not checked). Ensure your pet is in an airline-approved carrier if required by your airline.

Documents Checklist

  • Health certificate (original, issued within 10 days of travel)
  • Health certificate government endorsement (USDA APHIS or equivalent)
  • Import permit from Northern Mariana Islands
  • Microchip documentation (proof of ISO 11784/11785 chip and number)
  • Rabies vaccination certificate (original, showing date and vaccine name)
  • Proof of microchip placement (dated before rabies vaccination)
  • Copies of all documents (keep separate from originals)
  • Pet's identification photos (helpful if documents are questioned)

Key Requirements Explained

Microchip: The Foundation

The most common mistake I see is owners assuming their pet's existing microchip is ISO-compliant. It might not be. Northern Mariana Islands requires ISO 11784/11785 (15-digit) microchips. If your pet has a non-ISO chip, you have two options: provide your own compatible scanner at arrival, or get a new ISO chip. I always recommend the ISO chip—it's the global standard and eliminates headaches.

Critical timing: The microchip must be placed before the rabies vaccination. This is non-negotiable. The vet will record the microchip number on the vaccination certificate.

Rabies Vaccination: The 21-Day Rule

Rabies vaccination is required by virtually all countries for international pet travel. Your pet must be at least 12 weeks old at vaccination. After vaccination, there's a mandatory 21-day waiting period before travel. This means if you vaccinate on January 1st, your pet cannot travel until January 22nd at the earliest.

The vaccine must be current and administered by a licensed veterinarian. Boosters are required—if your pet's previous rabies vaccine is expired, a new booster must be given, and the 21-day clock restarts.

Health Certificate: The 10-Day Window

The health certificate is your pet's "passport" for travel. It must be issued by a licensed veterinarian and is valid for only 10 days from the issue date. This is why timing matters: issue it too early, and it expires before travel. Issue it too late, and you won't have time for government endorsement.

Here's what I tell my clients: issue the health certificate 7–10 days before departure. This gives you time to get government endorsement (3–5 business days in the US) while staying within the 10-day validity window.

The health certificate must be endorsed by your country's government veterinary authority. In the United States, this is USDA APHIS. In the United Kingdom, it's APHA. This is a separate step from the vet exam and takes additional time.

Import Permit: Apply Early

Northern Mariana Islands requires an import permit. The typical lead time is 30 days. Contact the Northern Mariana Islands government veterinary authority as soon as you know your travel date. You'll need:

  • Pet's name, age, breed, and color
  • Microchip number
  • Your contact information
  • Intended arrival date

Keep the permit number and approval letter. You'll present this at arrival.

Quarantine: Not Required (If Compliant)

Good news: Northern Mariana Islands does not require quarantine for pets that arrive with complete, valid documentation (microchip, rabies vaccine, health certificate, import permit). If all your paperwork is in order, your pet can go straight home.

Common Mistakes to Avoid

  • Non-ISO microchip: Verify your pet's chip is ISO 11784/11785 before travel. Don't assume.
  • Microchip after vaccination: Microchip must come first. If you vaccinate first, the chip placement won't be recorded on the vaccine certificate.
  • Expired health certificate: Issue it 7–10 days before travel, not earlier. The 10-day window is strict.
  • Missing government endorsement: The health certificate must be endorsed by your country's veterinary authority. This is not optional and takes time.
  • Late permit application: Apply 30 days before travel. Last-minute applications may be rejected.
  • Expired rabies vaccine: Confirm your pet's rabies vaccination is current. If expired, a new booster is required, and the 21-day waiting period restarts.
  • Traveling before the 21-day waiting period: After rabies vaccination, wait 21 days before travel. No exceptions.
  • Forgetting copies: Bring originals and copies. If a document is questioned, copies are your backup.

Special Considerations

Service Dogs

Trained service dogs (guide dogs, hearing dogs, mobility dogs) are recognized for travel purposes by most countries. However, service dog status does not waive import documentation. Your service dog must still have a microchip, rabies vaccination, health certificate, and import permit. Airlines typically require 48 hours advance notice for service dogs.

Emotional support animals (ESAs) are not recognized for travel purposes by government import authorities or airlines in most countries. If your pet is an ESA, it will be treated as a regular pet for import purposes.

Military Personnel

Military personnel typically follow standard civilian import rules. Import permits are generally not waived for military personnel. If you're relocating under PCS orders, check with your Transportation Management Office (TMO) for any streamlined processes, but expect to follow all standard requirements.

Breed Restrictions

Northern Mariana Islands has no breed restrictions for cats or dogs. All breeds are welcome, provided they meet health and documentation requirements.
