Can a Canadian Citizen Work in the USA? TN, H-1B, and L-1 Visas

A Canadian citizen can work in the USA, but only with valid work authorization tied to a specific job and employer. Four routes handle most cases: TN status under the USMCA, which qualified professionals can request at the border; the H-1B specialty occupation visa; the L-1 intracompany transfer; and the O-1 for people with extraordinary ability. Each has its own eligibility rules, fees, and time limits, and picking the wrong one means delays or a denial.

TN Status Under the USMCA

TN status is the reason most Canadians can start a U.S. job within days rather than months. It exists specifically to move qualified professionals between the three USMCA countries, and it covers more than 60 occupations, from engineering and accounting to forestry and graphic design.¹ The list is closed. Your job title and duties must match a listed profession, or you don’t qualify.

Not every TN occupation requires a four-year degree. Computer systems analysts, graphic designers, hotel managers, and interior designers can qualify with a post-secondary diploma or certificate plus three years of relevant experience.¹ Engineers and economists need a full bachelor’s degree or a state or provincial license. Management consultants can qualify by degree or by equivalent professional experience supported by a written credential. Read your profession’s specific requirement before assuming you’re covered.

Canadians apply for TN status directly at a U.S. port of entry or at a pre-clearance facility in a Canadian airport. You show up with your documentation, sit through a short interview with a Customs and Border Protection officer, pay an inspection fee, and walk away with work authorization the same day.²

TN status is granted for up to three years and can be renewed indefinitely, so there is no hard cap on how long you can stay if you keep qualifying.² The tradeoff is that TN is not dual-intent. You must maintain a residence in Canada and demonstrate a temporary stay. A CBP officer who suspects you intend to immigrate permanently can deny you on the spot.³

H-1B Specialty Occupation

The H-1B covers specialty occupations that require at least a bachelor’s degree or equivalent in a directly related field.⁴ Unlike TN, the H-1B is dual-intent, so you can pursue a green card while working under it.⁵ If your long-term plan is to settle in the U.S., the H-1B is far more flexible than TN, even though it is harder to get.

The obstacle is the annual cap. Congress set the regular H-1B cap at 65,000 per fiscal year, with an additional 20,000 slots for workers who hold a master’s degree or higher from a U.S. institution. Demand exceeds supply, so USCIS runs a lottery. Starting with FY 2027, the lottery is weighted by wage level: positions paying at wage level IV get four entries, level III gets three, level II gets two, and level I gets one.⁶

H-1B status maxes out at six years. After that you generally must leave the country, unless your employer has an approved immigrant visa petition or a labor certification that has been pending for at least 365 days, either of which can unlock one-year or three-year extensions past the six-year limit.⁷

L-1 Intracompany Transfer

If you already work for a company with offices in both Canada and the United States, the L-1 lets you transfer to the U.S. branch. You must have worked for the Canadian entity for at least one continuous year within the three years before you apply, and the U.S. role must be managerial, executive, or specialized-knowledge.⁸ The L-1 is dual intent, so pursuing permanent residence while on L-1 status is not a problem.⁵

O-1 Extraordinary Ability

The O-1 is reserved for individuals with extraordinary ability in the sciences, arts, education, business, or athletics. You need to show that you’ve risen to the top of your field through evidence like major awards, high-profile publications, or significant original contributions.⁹ The bar is high. In exchange, there’s no annual cap, so timing is not an issue the way it is with H-1B.

The Canadian Passport Advantage

Most foreign nationals must visit a U.S. consulate abroad to get a visa stamp in their passport before traveling. Canadian citizens are exempt from that requirement for most nonimmigrant classifications, including TN, H-1B, L-1, and O-1.¹⁰ A few categories still require a stamp, notably E treaty trader and investor visas, K fiancé visas, and S and V visas. For the main work classifications, you skip the consular step and either deal with CBP at the border or have your employer file a petition with USCIS.

Canada is also exempt from the general rule requiring a passport valid for six months beyond your intended stay. Canadians only need a passport valid for the period they plan to remain in the United States.¹¹ Applying with a passport that expires before your authorized stay ends can still create complications, so renewing early is the practical move.

Documents You’ll Need

Every application, whatever the classification, comes down to proving two things: that the job qualifies, and that you’re qualified to do it. Your core package:

A detailed employer support letter with the job title, duties, salary, and expected duration of the position. For TN applicants at the border, this is arguably your most important document.
Original diplomas, degree certificates, and transcripts. Degrees earned outside North America may need a formal credential evaluation to establish U.S. equivalency.
Proof of any professional license required to practice legally in the United States. Nursing, architecture, and engineering are common examples.
A valid Canadian passport covering the duration of your intended stay.¹¹

For classifications that require an employer-filed petition (H-1B, L-1, O-1), the employer submits Form I-129, Petition for a Nonimmigrant Worker, to USCIS.¹² Under the most recent USCIS fee rule, the base I-129 fee is $780 for H-1B, $1,385 for L, and $1,055 for O petitions. Most employers also owe a separate $600 Asylum Program Fee on top of the base filing fee.¹³ H-1B petitions carry additional fraud-prevention and workforce-training fees that can push the total well past $2,000 before attorney fees.

How the Process Actually Works

TN at the Border

TN applications are decided on the spot. You bring your documentation to a CBP officer at a land border crossing or a Canadian airport pre-clearance facility. The officer reviews everything, asks questions about your qualifications and the job, and decides then and there. If approved, you’re admitted immediately and can start working as soon as you enter.² Expect detailed questions. Officers regularly push back on vague job descriptions or duties that don’t clearly map to a listed profession. A well-drafted employer letter prevents most denials.

Petition-Based Classifications

H-1B, L-1, and O-1 cases move differently. The employer mails Form I-129 to USCIS, and standard processing takes several months. Employers who need a faster decision can file Form I-907 to request premium processing, which guarantees USCIS action within 15 business days.¹⁴ As of March 2026, the premium processing fee for Form I-129 is $2,965.¹⁵

When USCIS approves the petition, it sends the employer a Form I-797, Notice of Action.¹⁶ Because Canadians don’t need a visa stamp, you take that approval notice to a U.S. port of entry, where a CBP officer activates your status and admits you.

Bringing Your Spouse and Children

Each work classification has a corresponding dependent category for your spouse and unmarried children under 21. Whether your spouse can work varies dramatically by category.

TD (TN dependents): your spouse can live in the U.S. and study, but cannot work.
L-2 (L-1 dependents): your spouse is automatically work-authorized as of November 2021. An L-2 spouse with a Form I-94 showing the “L-2S” admission code can use that document as proof of work authorization.¹⁷
H-4 (H-1B dependents): your spouse can only work if you have an approved Form I-140 immigrant petition or have been granted H-1B status beyond the six-year limit. Even then, your spouse must apply for a separate Employment Authorization Document, which currently takes months to process, with no premium processing option.

If your spouse’s ability to earn matters to your family’s finances, this should factor into which classification you pursue. The gap between automatic L-2 work authorization and a months-long H-4 EAD wait is real.

After You Arrive

Your I-94 Arrival/Departure Record is the single most important document you’ll carry. It proves you’re legally in the U.S. and shows your authorized stay period. Download a digital copy from the CBP website or the CBP One app.¹⁸ Check it immediately for accuracy, particularly the admission class and the expiration date. Errors happen, and catching one early is far easier than fixing it after your employer has processed your paperwork.

Your employer must complete Form I-9 to verify your identity and work authorization.¹⁹ Present documents from the I-9 acceptable documents list within three business days of your first day on the job. Your Canadian passport and I-94 together typically satisfy this requirement.

You also need a Social Security Number to receive a paycheck. Visit a local Social Security Administration office with your passport and I-94 to apply. Processing usually takes two to four weeks, though some employers can begin payroll setup before the card arrives. Your SSN then becomes your permanent tax identifier for U.S. financial and government interactions.

One warning worth taking seriously. Your work authorization is tied to the specific employer and position described in your application. Switching employers or taking on significantly different duties requires a new application or an amendment to your existing status. Working for an unauthorized employer, even briefly, can jeopardize your immigration status in ways that are extremely difficult to undo.

Taxes and Social Security

Working in the United States creates U.S. tax obligations regardless of your citizenship. If you’re physically present in the U.S. for at least 31 days in the current year and 183 days over a three-year weighted period, the IRS treats you as a U.S. tax resident under the Substantial Presence Test. The weighted formula counts all days in the current year, one-third of the days in the prior year, and one-sixth of the days two years back.²⁰ Most full-time TN and H-1B workers easily hit that threshold, meaning the U.S. taxes their worldwide income the same way it taxes citizens.

Because Canada also taxes its residents on worldwide income, Canadians working in the U.S. face potential double taxation. The U.S.-Canada tax treaty addresses this primarily through foreign tax credits. You claim the credit on IRS Form 1116, which offsets your U.S. tax bill by the income tax you’ve already paid to Canada on the same income, or vice versa. The mechanics get complicated quickly if you have income sources in both countries, investment accounts, or rental property back home. A cross-border tax professional usually pays for itself.

The U.S. and Canada also have a Totalization Agreement to prevent workers from paying Social Security taxes to both countries at once. If your Canadian employer temporarily sends you to the U.S. and you remain covered by the Canada Pension Plan, you can request a Certificate of Coverage that exempts you from U.S. Social Security withholding. Apply through the Canada Revenue Agency using form CPT56, or through Retraite Québec if you’re covered by the Quebec Pension Plan. Your employer should keep the certificate on file in case of an IRS audit.²¹ If a U.S. employer hires you directly rather than sending you on temporary assignment, you’ll pay into the U.S. system instead. The agreement also lets you combine work credits earned in both countries to qualify for retirement benefits from either, which matters if you split your career.

Staying in Status

The consequences of overstaying or working without authorization are severe. If you accumulate more than 180 days of unlawful presence and then leave voluntarily, you’re barred from re-entering the United States for three years. Once unlawful presence reaches one year, the bar extends to ten.²² These bars apply automatically once you depart, and waivers are extremely difficult to obtain.

Working without authorization carries its own separate penalty. Under federal immigration law, unauthorized employment bars you from adjusting to permanent resident status inside the United States, even if you later marry a U.S. citizen or receive an employer-sponsored green card petition. Leaving and re-entering does not reset the bar.²³ A few weeks of unauthorized work can derail years of future immigration planning.

The most common way Canadians fall out of status is letting an I-94 expire without filing for an extension or leaving. If your TN status runs for three years and you lose track of the date, every day past expiration counts as unlawful presence. Set a calendar reminder at least six months before your authorization expires so you have time to renew, change status, or plan your departure.
