Ann Arbor sits in southeastern Michigan, and most international travelers reach the city through Detroit Metropolitan Wayne County Airport, roughly a thirty-minute drive to the east. Because Ann Arbor is a destination within the United States, entry formalities are governed entirely by U.S. federal immigration and customs law, regardless of which airport or land border crossing you use to enter the country. Whether you are arriving for the University of Michigan, the local food scene, or simply to spend time exploring, the documentary requirements are the same. The United States requires nearly all foreign nationals to hold either a valid visa or an approved electronic travel authorization before arrival. The specific requirement depends on your nationality, and rules do shift, so confirming your eligibility through official U.S. government immigration resources before booking travel is a step worth taking seriously. Showing up at the airport without the correct documentation typically means your airline will not let you board, or, if you reach the border, a Customs and Border Protection officer will deny you entry. For travelers heading to Ann Arbor, the practical entry point is usually the international arrivals hall at Detroit Metropolitan Airport, where CBP officers handle immigration inspection and customs screening. The process tends to be straightforward when documents are in order, though wait times vary depending on how many flights have arrived in close succession. Requirements do change, and any information here should be cross-checked against the official U.S. government immigration and CBP websites before you travel.

Visa Requirements

Entry permissions vary by nationality. Find your category below.

The United States operates a tiered entry system. Some nationalities may enter under the Visa Waiver Program with an approved ESTA, others need a nonimmigrant visa from an U.S. embassy or consulate, and certain passport holders can enter without either. Eligibility and permitted length of stay depend on your specific nationality and the purpose of your visit. The official U.S. immigration website is the definitive source for determining which category applies to you, and it is worth checking even if you have visited before, since agreements between countries are periodically revised.

Visa-Free Entry
Depends on nationality and the terms of the applicable bilateral agreement. Check the official U.S. immigration website for the permitted stay specific to your passport.

A limited number of nationalities may enter the United States without either a visa or an ESTA. These travelers typically need only a valid passport and may be subject to specific conditions at the port of entry. Whether your nationality qualifies for this arrangement depends on bilateral agreements that the U.S. government maintains.

Even travelers who do not need a visa or ESTA must carry a valid passport and may be asked standard questions by CBP officers about the purpose and duration of their visit. Entry is never guaranteed and remains at the discretion of the officer at the port of entry.

Electronic Travel Authorization (ETA/eVisa)
The permitted length of stay is determined by Visa Waiver Program terms for your nationality. Check the official immigration website for specifics.

ESTA, the Electronic System for Travel Authorization, is required for nationals of Visa Waiver Program countries traveling to the United States without a visa, whether by air, sea, or land. The ESTA is not a visa but an advance screening that must be approved before departure. It is the most common pathway for short-term visitors from eligible countries.

How to Apply: Apply through the official ESTA website before travel. Processing is often rapid, sometimes within minutes. But it is wise to submit your application well ahead of departure in case additional review is needed. The only legitimate application portal is the official CBP ESTA site. Third-party websites frequently charge significantly more for the same application and offer no additional benefit.
Cost: A per-application processing fee applies for each approved authorization. Apply only through the official ESTA website to see the current fee and to avoid inflated charges from unauthorized third-party sites.

An approved ESTA is generally valid for multiple trips over a two-year period, or until your passport expires, whichever comes first. If your ESTA application is denied, you will need to apply for a visa through an U.S. embassy or consulate. Changes in personal circumstances, such as a new passport or a change in eligibility, may require a new ESTA application even within the two-year window.

Visa Required
The length of stay is determined by the CBP officer at the port of entry, based on your visa type and the stated purpose of your visit. This is recorded on your admission stamp or electronic I-94 record.

Nationals of countries not participating in the Visa Waiver Program and not covered by other visa-free agreements must obtain a nonimmigrant visa before traveling to the United States. The B-2 visitor visa covers tourism and leisure travel, while the B-1 is for business purposes. Other specialized visa categories exist for students, workers, and specific program participants.

How to Apply: Apply at the U.S. embassy or consulate in your home country or country of legal residence. The process typically involves completing an online application, paying the applicable fee, scheduling and attending an in-person interview, and waiting for processing. Wait times for interview appointments vary considerably by location and season, so beginning well in advance is advisable.

Visa approval is not guaranteed, and possessing a valid visa does not guarantee entry. The CBP officer at the port of entry makes the final decision on admission. Be prepared to demonstrate ties to your home country and a clear intent to depart the United States at the end of your authorized stay.

Arrival Process

Most international visitors bound for Ann Arbor clear immigration and customs at Detroit Metropolitan Wayne County Airport. If you are connecting through another U.S. airport, you will clear CBP at your first point of entry into the United States, not at your final domestic destination. This means you will collect your checked luggage, pass through customs, and re-check your bags before your connecting flight.

1
Pre-departure document check
Before heading to the airport, confirm you have a valid passport, an approved ESTA or valid U.S. visa as applicable, and evidence of onward or return travel. Airlines are legally required to verify your travel authorization before allowing you to board an U.S.-bound flight, and they will deny boarding if your documentation is incomplete.
2
ESTA verification for Visa Waiver Program travelers
If you are traveling under the Visa Waiver Program, your ESTA must be approved before you depart. Apply through the official ESTA website. Approvals often come quickly. Allow time for potential delays. Your airline will check your ESTA status at the gate.
3
Arrival and immigration inspection
On landing at your U.S. port of entry, follow signs to the CBP inspection area. Have your passport and any supporting documents accessible. A CBP officer will review your travel authorization, ask about the purpose and expected duration of your visit, and collect biometric data including fingerprints and a photograph. Automated kiosks may be available at some airports for eligible travelers, which can shorten waiting time.
4
Customs and agriculture screening
You will need to declare items you are bringing into the country, either through an electronic kiosk or a paper declaration form. Be truthful about everything you are carrying, food, plant material, and agricultural products. U.S. agriculture inspectors are thorough, and undeclared items that are discovered tend to create more problems than declaring them upfront would have.
5
Baggage collection and exit
Collect your checked luggage and proceed to the customs exit. A percentage of travelers are selected for secondary inspection, which involves a more detailed look at belongings and documents. This is routine and not necessarily an indication of a problem. Answer questions straightforwardly and the process typically moves along without difficulty.
6
Onward travel to Ann Arbor
After clearing customs at Detroit Metropolitan Airport, Ann Arbor is roughly a thirty-minute drive west along Interstate 94. Ground transportation options include rental car counters in the airport terminal, ride-hailing services, and scheduled shuttle services that run between the airport and Ann Arbor throughout the day.

Documents to Have Ready

Valid passport
Your passport should generally be valid for at least six months beyond your intended stay, though certain nationalities are exempt from this requirement under bilateral agreements. Confirm the specific validity requirement for your passport with the nearest U.S. embassy or consulate.
Approved ESTA or valid U.S. visa
Visa Waiver Program travelers must hold an approved ESTA before departure. Apply only through the official ESTA website. All other foreign nationals who are not exempt from visa requirements need a valid visa in their passport issued by an U.S. embassy or consulate.
Evidence of onward or return travel
CBP officers may ask to see proof that you intend to leave the United States, such as a return flight itinerary or onward booking. Having this accessible on your phone or in printed form saves time at the inspection counter.
Proof of accommodation in Ann Arbor
A hotel reservation confirmation, a letter from your host, or the address where you will be staying in Ann Arbor. Officers do not always ask for this. But having it ready demonstrates preparation and can smooth the interaction.
Evidence of financial means
Officers may ask how you plan to support yourself during your visit. A recent bank statement, credit card, or letter from an employer or sponsor can serve this purpose. It is not always requested. But it is better to have it available than to be caught without it.

Tips for Smooth Entry

Answer CBP officers' questions directly and concisely. Volunteering a great deal of unsolicited detail can prolong the interaction just as much as being evasive.
Keep all travel documents, including your accommodation booking and return ticket, in your carry-on rather than your checked luggage. You will need them before you can reach your bags.
If you are connecting to a domestic flight after clearing CBP at another U.S. airport, allow at least two to three hours between flights for the immigration and customs process, during peak arrival windows in the morning and early afternoon.
Save your Ann Arbor accommodation address and ground transportation details on your phone before departure. Mobile service is typically available immediately on landing at Detroit Metropolitan Airport.
Dress comfortably but presentably. While there is no dress code for immigration, first impressions are human nature, and officers process hundreds of travelers per shift.

Customs & Duty-Free

U.S. Customs and Border Protection enforces detailed rules on what travelers may bring into the country. The general principle is straightforward: declare everything you are bringing, and let the officer sort out what is dutiable and what is not. The penalties for failing to declare items are considerably harsher than any duty you might owe, and undeclared goods discovered during inspection can be seized outright.

Alcohol
1 liter of alcoholic beverages per traveler
You must be at least 21 years old. Michigan, where Ann Arbor is located, generally follows the federal allowance. Quantities above the allowance may be brought in but are subject to duty and state taxes.
Tobacco
200 cigarettes or 100 cigars per traveler
You must meet the minimum age requirement. Cuban-origin tobacco products may be subject to trade restrictions that change periodically. Check current regulations before packing them.
Currency
No limit on the amount of currency you may bring into the United States. But amounts above the reporting threshold must be declared to CBP
This rule covers cash in any denomination or currency, plus traveler's checks, money orders, and certain negotiable instruments. The declaration requirement applies to the combined total carried by your traveling party, not per person. Fail to declare and you face mandatory seizure. Legitimacy of the funds does not matter.
Gifts/Goods
A duty-free personal exemption covers goods acquired abroad. Your value threshold depends on residency status and arrival origin.
Goods above the exemption face duty at varying rates by item. Commercial merchandise uses a separate tariff schedule. Keep receipts for major purchases. They simplify declarations.

Prohibited Items

  • Most meat, poultry, and pork products from outside the United States face restriction under animal disease-control regulations
  • Fresh fruits, vegetables, and plants from most countries are barred unless they clear USDA agricultural inspection at the port of entry
  • Narcotics and controlled substances without a valid U.S. prescription
  • Counterfeit goods, including branded knockoffs of any kind
  • Products from endangered species protected under CITES are prohibited. This includes ivory, tortoiseshell, and certain exotic leathers
  • Absinthe containing thujone above the permitted concentration
  • Switchblade knives and certain other weapons prohibited under federal law

Restricted Items

  • Prescription medications exceeding personal supply need documentation. Carry your prescription or a letter from your physician. Keep pills in original labeled containers.
  • Firearms and ammunition must be declared and may need specific permits. Foreign nationals face extra restrictions on firearm importation
  • Certain food products, including cured meats and hard cheeses from specific countries, may clear after USDA inspection
  • Cultural artifacts and antiquities may need export permits from the origin country. They can face U.S. import restrictions under bilateral cultural property agreements
  • Alcohol above the duty-free allowance is permitted. It faces duty, federal excise tax, and Michigan state taxes

Health Requirements

The United States does not impose extensive health documentation on most arriving travelers. A few points matter before your Ann Arbor trip. Know the rules on vaccination records and medical care access.

Required Vaccinations

  • No vaccinations are routinely required for short-term visitors entering the United States. One exception stands out. Yellow fever vaccination is required for travelers arriving from countries or regions with yellow fever transmission. Carry a valid International Certificate of Vaccination or Prophylaxis. Port officials may request it.

Recommended Vaccinations

  • Keep routine vaccinations current before international travel. This includes measles-mumps-rubella, diphtheria-tetanus-pertussis, varicella, polio, and seasonal influenza
  • Hepatitis An and Hepatitis B vaccinations are generally recommended for international travelers to the United States
  • See your physician or a travel health clinic. Get personalized recommendations based on your health history and itinerary

Health Insurance

The United States has no legal requirement for visitors to carry health insurance. Traveling without it is a major financial risk. Medical care in Ann Arbor is excellent. The University of Michigan Health System anchors it, one of the top academic medical centers in the country. Treatment costs without insurance can be steep even for minor issues. Buy a travel health insurance policy covering emergency treatment, hospitalization, and medical evacuation. Confirm before departure that your policy covers the United States specifically. Understand the claims process.

Current Health Requirements: Travelers arriving from countries or regions with yellow fever transmission risk may need to show a valid yellow fever vaccination certificate at arrival. Otherwise, the United States does not currently require health documentation at the border for most short-term visitors. Requirements change. Check guidance from the U.S. Centers for Disease Control and Prevention for your origin country before departure. Carry prescription medications in original containers. Bring a copy of your prescription. CBP officers may ask about medications during inspection.

Important Contacts

Essential resources for your trip.

Embassy/Consulate
Your country's embassy is most likely in Washington, D.C. Consular offices sit in major U.S. cities. Detroit and Chicago are the nearest consular cities to Ann Arbor for most countries.
Find your nearest embassy or consulate through your government's foreign affairs website before you travel. Register your trip with your government's travel registration program if available. This lets them reach you in an emergency.
Immigration Authority
U.S. Customs and Border Protection handles all matters at ports of entry. The U.S. Department of State processes visa applications through embassies and consulates abroad. U.S. Citizenship and Immigration Services handles extensions of stay and changes of status from within the country.
For visa or travel authorization questions, check the official U.S. Department of State website. For questions about what you may bring into the country, check the CBP website.
Emergency
Dial 911 for police, fire, or medical emergencies. This works anywhere in Ann Arbor and throughout the United States.
911 works from any phone, including mobile phones without an active local plan. For non-emergency police matters in Ann Arbor, contact the Ann Arbor Police Department through local directory services.

Special Situations

Additional requirements for specific circumstances.

Traveling with Children

Traveling with a child who is not your own? Bring a notarized letter of consent from the absent parent or legal guardian. Single parents without the other parent present need this too. CBP officers will not always ask. Refusal to show it causes delays. Sometimes, entry denial follows. The letter needs specifics: the child's full name and date of birth, your full name and relationship, the absent parent's consent for this exact trip, and contact details for verification. Adopted children require adoption paperwork. Unaccompanied minors face airline rules plus CBP requirements. Confirm both with your carrier before you book.

Traveling with Pets

Bringing a pet to Ann Arbor takes advance planning. Dogs entering the United States must appear healthy on arrival. They may need a valid rabies vaccination certificate. Requirements depend on origin country and vaccination history. The CDC updates dog import rules periodically. Rules vary by departure country. Check current CDC guidance for your specific origin. Cats face fewer federal entry requirements. Keep their vaccinations current anyway. Other animals, birds, reptiles, and exotic species fall under USDA and U.S. Fish and Wildlife Service regulations. Import permits may be required. Michigan state law adds possible requirements. Contact your airline early. Ask about carrier specifications. Ask about in-cabin versus cargo-hold transport policies.

Extended Stays

Want to stay longer than authorized? Apply for an extension through U.S. Citizenship and Immigration Services. File before your current stay expires. Overstaying brings serious consequences. Future entry bars can last years. Longer-term stays need specific visas. Studying at the University of Michigan requires a student visa. Working in Ann Arbor requires a work visa. Research stays need exchange visitor programs. Each category has its own application process. Each requires institutional or employer sponsorship. Start months ahead. Processing times drag on.
