The 4 rules every Canadian snowbird should know

6 months per visit

Canadian visitors are usually admitted for up to 6 months at a time. The border officer decides how long you can stay.

About 6 months a year

Spending more than about 6 months a year in the US can lead to questions at the border, and suggests you may be living there.

The 30-day registration rule

Canadians aged 14 and older who stay 30 days or more must be registered. Flying in, or getting an I-94 record at a land crossing, counts.

The 183-day tax test

The US counts this year’s days, plus a third of last year’s and a sixth of the year before. At 183 or more, you may be treated as a US tax resident unless you file Form 8840.

Crossing the border in 2026: what to know

Carry proof of your ties to Canada

Bring your provincial health card, proof of your Canadian address, and your return date. Officers may ask how long you plan to stay and why.

Know the registration rule

Staying 30 days or more? Make sure you’re registered. Flying in, or getting an I-94 record at a land crossing, counts.

Devices can be checked

US border officers can inspect phones and laptops. Travel with what you need, and answer questions calmly and truthfully.

Be careful with the past

A past record, including an old DUI or drug charge, can make you inadmissible. Never guess or give inaccurate answers. Get advice before you travel.

Snowbird days: common questions

How many days can a Canadian snowbird stay in the US?

Canadian visitors are usually admitted for up to 6 months at a time. Spending more than about 6 months a year in the US can lead to questions at the border.

Does every part of a day count as a day in the US?

For the US 183-day tax test, yes. Any part of a day you're in the US generally counts as a full day, including the days you arrive and leave.

How is the 183-day substantial presence test calculated?

Add all your days in the US this year, a third of your days last year, and a sixth of your days the year before. If the total is 183 or more, and you spent at least 31 days in the US this year, you meet the test.

What is IRS Form 8840?

Form 8840, the Closer Connection Exception Statement, lets many Canadian snowbirds who meet the 183-day test show they have closer ties to Canada, so they aren't treated as US tax residents. It's usually due by June 15 of the following year.

Do snowbirds need to register with the US government?

Canadians aged 14 and older who stay in the US for 30 days or more must be registered. If you fly in, or receive an I-94 record at a land crossing, you're already registered.

Can I stay longer than 6 months a year?

Not as a visitor. To spend more time in the US, you'd need another status, such as a green card through a US citizen son or daughter, an E-2 business visa or an EB-5 investment.

What should snowbirds bring when crossing the border?

Bring your passport, provincial health card, proof of your Canadian address and your planned return date. Be ready to explain how long you plan to stay, and answer questions calmly and truthfully.

What if I was refused entry to the US before?

Don't try to cross again without advice. A past refusal, record or overstay can affect future trips, and some problems can be fixed with a waiver.
