Yes, a Canadian citizen can work in the United States, but only after obtaining a status that authorizes the specific job. For most professionals the fastest route is TN status under the United States-Mexico-Canada Agreement, which is filed at the border and covers roughly 60 designated occupations. Other categories include the H-1B for specialty occupations, the L-1 for intracompany transfers, and the O-1 for people with extraordinary ability. Choosing the right one depends on the job, the employer, and whether you eventually want a green card.
Business Visits Versus Working
Canadians generally don’t need a visa for short business trips.1U.S. Department of State. Citizens of Canada and Bermuda Attending meetings, negotiating contracts, and going to conferences are permitted business visitor activities.2U.S. Department of State. Business The line is drawn at productive work: you cannot perform day-to-day duties for a U.S. employer, work from a U.S. office on a regular basis, or provide on-site services to U.S. clients without authorization.
Working remotely from Canada for a U.S. company is different. U.S. immigration law is triggered by physical presence on U.S. soil, so a fully remote arrangement generally doesn’t require a work visa. Once the role calls for you to cross the border for anything more than meetings or conferences, you need proper status.
TN Status Under the USMCA
TN is the workhorse category for Canadian professionals. It exists under the trade agreement between the United States, Mexico, and Canada, and it’s limited to citizens of those two countries working in jobs listed in Appendix 2 to Annex 16-A of the USMCA.3Office of the U.S. Trade Representative. USMCA Chapter 16 Temporary Entry for Business Persons There is no annual cap and no lottery, and Canadians can apply directly at the border without a pre-filed petition.
You must have a prearranged full-time or part-time job with a U.S. employer.4U.S. Citizenship and Immigration Services. TN USMCA Professionals Self-employment is prohibited: rendering services to a company you solely or predominantly own counts as self-employment and disqualifies you.5eCFR. 8 CFR 214.6 – Citizens of Canada or Mexico Seeking Professional Business Activities Canadians who want to run their own U.S. business should look at E-1 treaty trader or E-2 treaty investor status instead.
Each admission lasts up to three years, and there is no cap on renewals as long as your stay remains temporary.6U.S. Citizenship and Immigration Services. USCIS Policy Manual Volume 2 Part P Chapter 4 – Extension of Stay and Change of Status That indefinite-renewal option is a real advantage. The tradeoff is that TN status does not formally allow dual intent, so you cannot enter the country with the immediate purpose of getting a green card. Filing an adjustment of status application while on TN can jeopardize future extensions or re-entry. Canadians who want a path to permanent residency often switch to H-1B or L-1 first, since those categories allow dual intent.
Which Jobs Qualify for TN
The USMCA list covers about 60 occupations across four broad groups. Most require at least a bachelor’s degree, though some accept a post-secondary credential combined with relevant experience.
- General professions, including accountant, architect, computer systems analyst, economist, engineer, graphic designer, hotel manager, interior designer, land surveyor, landscape architect, lawyer, management consultant, mathematician, social worker, urban planner, and technical publications writer.
- Medical and allied professions, including dentist, dietitian, pharmacist, physician (teaching or research only), physical therapist, psychologist, registered nurse, and veterinarian.
- Scientists, including biologist, chemist, geologist, meteorologist, geneticist, and entomologist, among others.
- Teachers at the college, seminary, and university level.
Some professions have alternative qualification paths. A computer systems analyst, for example, can qualify with a post-secondary diploma and three years of experience in place of a bachelor’s degree.3Office of the U.S. Trade Representative. USMCA Chapter 16 Temporary Entry for Business Persons If your job isn’t on the list, TN isn’t an option no matter how qualified you are.
H-1B Specialty Occupations
The H-1B is open to professionals from any country whose job requires the theoretical and practical application of specialized knowledge and at least a bachelor’s degree in a directly related field.7U.S. Citizenship and Immigration Services. H-1B Specialty Occupations Common fields include software engineering, finance, biotech research, and healthcare specialties.8U.S. Department of Labor. H-1B, H-1B1 and E-3 Specialty (Professional) Workers
The catch is the annual cap. Congress limits new H-1B approvals to 65,000 per fiscal year, plus 20,000 more for applicants with a U.S. master’s degree or higher.9U.S. Citizenship and Immigration Services. USCIS Reaches Fiscal Year 2026 H-1B Cap Demand routinely exceeds supply, so USCIS runs a registration lottery. Your employer files Form I-129 and pays the fees. If selected and approved, you can stay up to six years. Extensions beyond that are possible in one-year or three-year increments if your employer has started the green card process on your behalf.10U.S. Citizenship and Immigration Services. FAQs for Individuals in H-1B Nonimmigrant Status
Because H-1B allows dual intent, it’s often the preferred vehicle for Canadians who eventually want permanent residency. Many professionals start on TN and switch to H-1B once their employer is ready to sponsor a green card.
L-1 Intracompany Transfers
If you already work for a company with offices in both Canada and the United States, the L-1 lets your employer transfer you without the H-1B lottery. The L-1A covers executives and managers; the L-1B covers employees with specialized knowledge of the company’s products, services, or procedures.11U.S. Citizenship and Immigration Services. L-1A Intracompany Transferee Executive or Manager You must have worked continuously for the foreign office for at least one year within the three years before your admission.
L-1A executives and managers can remain up to seven years. L-1B specialized-knowledge workers are capped at five. Time previously spent in H status counts against these limits.12U.S. Department of State Foreign Affairs Manual. 9 FAM 402.12 – Intracompany Transferees – L Visas L-1 status also allows dual intent, making it another natural bridge to permanent residency.
O-1 Extraordinary Ability
The O-1 is narrow. It’s for individuals at the top of their field in the sciences, arts, education, business, or athletics.13U.S. Citizenship and Immigration Services. O-1 Visa – Individuals with Extraordinary Ability or Achievement “Extraordinary” means national or international recognition backed by concrete evidence: major awards, published research, high salary relative to peers, or a substantial body of original contributions. Most applicants must satisfy at least three of the regulatory criteria. It isn’t realistic for most professionals, but for those who qualify, it has no annual cap and no maximum period of stay; extensions continue as long as the work does.
How You Actually Apply
A big procedural advantage for TN applicants is that no petition is required. You apply directly at a U.S. port of entry or at a pre-clearance facility inside a Canadian airport, presenting your documentation to a Customs and Border Protection officer.14U.S. Customs and Border Protection. Traveling on a TN or L1 Visa from Canada The officer reviews your papers and, if satisfied, issues an I-94 showing your class of admission and the expiration of your authorized stay. Be ready to pay applicable processing fees on the spot.4U.S. Citizenship and Immigration Services. TN USMCA Professionals
For H-1B, L-1, and O-1, your employer must first file Form I-129 with USCIS and receive approval before you can enter.15U.S. Citizenship and Immigration Services. Form I-129 – Petition for a Nonimmigrant Worker
What to Bring
- A valid Canadian passport, valid through at least the date you plan to leave the United States. Canadians are not subject to the six-month validity rule that applies to many other nationalities.16U.S. Customs and Border Protection. Visiting the U.S. – Documents Required for Canadian Citizens to Enter the U.S.
- An employer support letter on company letterhead describing the job title, duties, duration, and salary. For TN, the letter should explain how the role fits one of the designated USMCA professions.
- Original diplomas, transcripts, or professional licenses proving you meet the qualifications.
- A copy of the I-797 approval notice if your employer has already filed an I-129 for H-1B, L-1, or O-1 status.
CBP officers have broad discretion, and vague or incomplete documentation is the most common reason for denial. The employer letter matters most; ambiguity about how the job fits the visa category is where problems usually start.
Spouse and Children
Your spouse and unmarried children under 21 can accompany you under a derivative status tied to your category. TN workers’ families enter on TD, H-1B families on H-4, and L-1 families on L-2. In each case, family members need proof of the relationship, such as marriage and birth certificates.
Dependents can live in the United States and attend school, but most cannot work without separate authorization. TD dependents have no path to employment authorization. H-4 spouses have one important exception: if the H-1B worker is the beneficiary of an approved I-140 immigrant petition, or has an H-1B extension beyond the standard six-year limit under the American Competitiveness in the Twenty-first Century Act, the H-4 spouse can apply for an Employment Authorization Document on Form I-765.17U.S. Citizenship and Immigration Services. Employment Authorization for Certain H-4 Dependent Spouses The spouse cannot begin working until the EAD is approved and in hand.
Every derivative status depends on the primary worker keeping valid status. If the principal’s authorization lapses or is revoked, the family loses status too.
Taxes and Social Security
Working in the United States triggers U.S. tax obligations that catch many Canadians off guard. If you meet the IRS substantial presence test, you’re treated as a U.S. resident for tax purposes and must report worldwide income. The test is met if you’re physically present at least 31 days in the current year and at least 183 days over a three-year period, counting all days in the current year, one-third of the days in the prior year, and one-sixth of the days two years back.18Internal Revenue Service. Substantial Presence Test Certain days don’t count, including days commuting from a Canadian residence and days you couldn’t leave because of a medical condition that arose in the United States.
Even if you meet the test, a closer connection exception may let you be treated as a nonresident if you maintain stronger ties to Canada. The U.S.-Canada tax treaty also has relief mechanisms against double taxation. These provisions get technical fast, and professional tax advice is usually worth it.
You’ll also need a Social Security number before your employer can run payroll. Only noncitizens with work authorization can get one. Apply at a local Social Security Administration office with your passport and your I-94 showing a class of admission that permits work.19Social Security Administration. Learn What Documents You Will Need to Get a Social Security Card There is no application fee.
What Happens If You Work Without Authorization
Unauthorized employment reaches well beyond the immediate job. Under federal immigration policy, anyone who has worked without authorization is barred from adjusting to permanent resident status, with limited exceptions. The bar applies regardless of when the unauthorized work occurred; even a brief stint years earlier can block a future green card application.20U.S. Citizenship and Immigration Services. USCIS Policy Manual Volume 7 Part B Chapter 6 – Unauthorized Employment Leaving and re-entering does not erase it.
Beyond the adjustment bar, unauthorized work can lead to removal proceedings and inadmissibility for future visas. CBP officers have access to employment records and can flag inconsistencies on later crossings. For Canadians who cross the border often, a single misstep here can create years of complications.
