What You Need to Cross Into the United States From Niagara Falls, Ontario

From the Canadian shore, New York is close enough to see. Getting there by car is usually a short drive over the Rainbow Bridge, the Lewiston-Queenston Bridge or the Peace Bridge, followed by a stop at a US Customs and Border Protection (CBP) booth. What you need to cross into the US depends on who you are: an American returning home, a Canadian on a day trip, or a visitor from overseas who flew into Toronto. This page sets out the October 2026 rules. NiagaraFallsLimo.net chauffeurs drive the crossing with you every day, but each passenger answers for their own documents.

What do I need to cross into the US at Niagara?

WHTI is the Western Hemisphere Travel Initiative, the US rule that sets which documents work at land and sea crossings. CBP lists them on its WHTI page.

US citizens returning home

By land or sea, CBP accepts a valid:

• US passport;
• US passport card, which is valid for land and sea crossings but not for international flights;
• enhanced driver's licence (issued by some states);
• trusted traveller card: NEXUS, SENTRI or FAST;
• US military ID when travelling on official orders, and a few specialist documents.

If you arrived in Canada by plane on a passport book and plan to fly home from Buffalo, bring the book, not just the card.

Canadian citizens

CBP accepts a valid Canadian passport, an enhanced driver's licence, or a NEXUS, SENTRI or FAST card from Canadian citizens. Canada's Global Affairs department adds a few points worth knowing before a trip:

• Canadians can usually stay in the US for up to six months without a visa and must state how long they intend to stay.
• Dual Canada–US citizens are required by US law to enter the US on their US passport.
• US officers may search phones and laptops and may ask for passwords.
• A Canadian pardon (record suspension) is not recognized under US law.

Do not assume an Ontario enhanced driver's licence is available to you; check with the province first. The passport is the safe choice.

Canadians staying 30 days or longer

This rule surprises winter travellers and long-stay visitors. US Citizenship and Immigration Services (USCIS) says non-citizens aged 14 or older who stay in the United States for 30 days or longer must be registered, and it names Canadian visitors who entered at a land port without being issued an I-94 as a group that may not be registered automatically. Registration is filed online through a USCIS account using Form G-325R, one account per person, and the rule applies to each stay of 30 days or more. Parents must make sure children under 14 are registered. Details are on the USCIS alien registration page.

For a Niagara day trip or a weekend in Buffalo, none of this applies.

Visitors from overseas: visa or ESTA

Travellers who are neither US nor Canadian citizens need a valid passport and a US entry authorization.

• Visa Waiver Program nationals need an approved Electronic System for Travel Authorization (ESTA) before reaching a US land border. CBP's I-94 page states this directly, and CBP's Buffalo field office has reminded travellers to apply as soon as plans begin and no later than 72 hours before arrival. An approved ESTA is valid for two years or until the passport expires. As of October 16, 2026 the ESTA fee is US$40.62.
• Everyone else needs the appropriate US visa in their passport.
• Permanent residents of Canada who are not Canadian citizens enter on their own country's passport, with a visa or an ESTA as their nationality requires. A Canadian PR card alone is not a US entry document.

Plan this before leaving home. A Visa Waiver traveller who reaches the Rainbow Bridge without an approved ESTA is in for a long afternoon. Our international visitors guide covers two-country itineraries.

The I-94 at a land border

Most non-citizens other than Canadians are issued an I-94 arrival record. At land crossings CBP now issues it electronically, with no paper stub. You can start it before you travel:

• apply on the official I-94 website or in the CBP Link app;
• a provisional I-94 must be completed in person at the border within seven days, or it expires and you pay again;
• the land-border I-94 fee is US$30 as of 2026.

Starting the I-94 in advance saves time at the booth, but you still appear in person and the officer still decides on admission. Note that CBP Home is a different app, not an I-94 app.

Biometrics at US land crossings

Since December 26, 2025, a Department of Homeland Security rule allows CBP to photograph non-citizens, including Canadians, on entry to and exit from the United States at land ports. Expect a camera at the booth. It is routine and needs nothing from you beyond looking at the lens when asked.

US green-card holders

WHTI does not change the rule for US lawful permanent residents. Carry your permanent resident card (Form I-551). An enhanced permanent resident card also works in the US-bound Ready Lane.

Children

CBP's WHTI rules say that US and Canadian citizen children under 16 arriving by land or sea need only a birth certificate or other proof of citizenship. CBP accepts an original, a photocopy or a certified copy of that birth certificate. The age rises to under 19 for children travelling with a school, religious or youth group, whose supervising adult should carry a letter on organization letterhead and a signed statement confirming parental consent for each child.

When a child travels with only one parent, CBP's visitor guide suggests a notarized note from the other parent. Our crossing with children page explains letters and custody documents for both directions.

Ready Lanes and RFID cards

At some Niagara crossings CBP opens a Ready Lane for US-bound cars when every traveller aged 16 or older carries an RFID card: a US passport card, an enhanced driver's licence, an enhanced permanent resident card, or a NEXUS, SENTRI, Global Entry or FAST card. CBP's feeds have shown Ready Lane hours on weekday afternoons, Monday through Thursday, at the Peace and Rainbow bridges. A passport book alone does not qualify.

NEXUS lanes are stricter still: every occupant, including the driver, must be a member. Our NEXUS guide covers the lane rules.

What not to bring into the US

• Cannabis: CBP says marijuana, medical or recreational, remains illegal under US federal law. Arriving with it may mean seizure, fines or arrest, and may affect admissibility. Canada's government warns that past use or work in the cannabis industry can also make a Canadian inadmissible.
• Goods: declare what you bring. Returning US residents get a US$800 duty-free exemption once every 31 days after 48 hours away, and US$200 for shorter trips.
• Food and plants: declare them; officers decide what may enter.

More on allowances is on our duty-free and declarations page.

Crossing into the US in a chauffeured car

On the day:

1. Your chauffeur collects you at your hotel, a winery, a station or the airport and chooses the bridge from the live CBP readings.
2. Have every passport or card, and any I-94 confirmation, in hand before the booth.
3. The officer may ask each person about the purpose and length of the trip and may photograph non-citizens. Answer for yourself.
4. Once cleared, the chauffeur continues to your drop-off in New York.

We never promise a crossing time. We do provide licensed, commercially insured chauffeurs and a fixed fare. Our cross-border car service explains the rest, and our border wait times guide shows where to read the queues.

Ways to cross into the US compared

When another option is the better choice

For a few hours at the American Falls, walk the Rainbow Bridge; it is the only Niagara crossing with a pedestrian walkway. Drivers heading into the US pay no bridge toll at all. A solo traveller on a timetable-friendly trip can take the bus or the Amtrak Maple Leaf, which stops on both sides of the river.

Book a chauffeur when you need to reach BUF on time, when luggage or car seats are involved, when the whole group should arrive together, or when the trip ends somewhere a bus does not go. Our chauffeur vs taxi vs rideshare guide sets out each option honestly.

Who this page is for

• Individuals: Canadian business travellers heading to Buffalo, and overseas visitors checking ESTA before a two-country trip.
• Couples: a day on the American side, or a flight home from Buffalo.
• Families: parents checking children's birth certificates and consent letters; see families.
• Groups: fans heading to Highmark Stadium, wedding guests, and school groups under 19 with a supervising adult.
