US Work Visa for Canadian Citizens: TN, H-1B, L-1 & O-1

Canadian citizens have more ways into the U.S. workforce than nationals of almost any other country. The main options for a US work visa for Canadian citizens are TN status under the USMCA, the H-1B specialty occupation visa, the L-1 intracompany transfer visa, the O-1 for people with extraordinary ability, and the E-2 treaty investor visa. Which one fits depends on your profession, whether you have a U.S. employer or your own business, and whether you eventually want a green card.

TN Status Under the USMCA

TN is the fastest route and the one built specifically for Canadians and Mexicans. You do not need your employer to file a petition with USCIS first. You show up at a U.S. port of entry or pre-clearance facility, present your documents to a Customs and Border Protection officer, and if approved, walk away the same day with authorization to work for up to three years.¹

The trade-off is that your job must fall within a list of roughly 60 approved professions. Engineers, accountants, computer systems analysts, scientists, pharmacists, architects, foresters, graphic designers, and management consultants are on it. Each occupation has its own credential rule, and CBP officers check them closely.²

A few examples of how the credentials work:

Engineers need a bachelor’s degree in engineering, or a state or provincial license to practice.
Accountants need a bachelor’s degree, or a professional designation such as CPA, CA, CGA, or CMA.
Computer systems analysts need a bachelor’s degree, or a post-secondary diploma or certificate combined with three years of experience.
Management consultants need a bachelor’s degree, or five years of experience in the field supported by a professional credential or statement.

Two restrictions catch people. First, TN status requires a prearranged job with a U.S. employer, and self-employment does not qualify. If you own or control the company that would employ you, CBP will deny the application.³ Second, TN is not a dual-intent visa. You can renew in three-year increments with no formal cap, but you must maintain the intent to return to Canada eventually.¹ That becomes a real problem if you later want a green card.

H-1B for Specialty Occupations

If your job is not on the USMCA list, the H-1B is usually the next stop. It covers any “specialty occupation” that requires the theoretical and practical application of a body of specialized knowledge and at least a bachelor’s degree in a specific field.⁴ The position itself has to require the degree, not just the person filling it.

Your employer files Form I-129 with USCIS and must first submit a Labor Condition Application to the Department of Labor certifying that your wages meet the prevailing rate for the occupation and location.⁵

The H-1B is capped at 65,000 visas a year, plus another 20,000 reserved for holders of a U.S. master’s degree or higher. Demand outstrips supply, so USCIS runs a lottery. For fiscal year 2027, with employment starting October 2026, the registration window ran from March 4 to March 19, 2026. Canadians go into the same lottery as everyone else. If your registration is not selected, you cannot start H-1B work that fiscal year.

Some employers are cap-exempt, including universities, nonprofit research organizations, and government research organizations. A job at one of these institutions means the H-1B petition can be filed any time, no lottery involved.

The H-1B’s biggest structural advantage over TN is dual intent: you can openly pursue permanent residence while on H-1B without jeopardizing your status. For Canadians who want a long-term future in the U.S., that often matters more than the lottery hassle.

L-1 for Company Transfers

The L-1 is for employees of multinational companies moving from a foreign office to a related U.S. office. You must have worked for the company abroad for at least one continuous year within the three years before your transfer, and you must be coming to the U.S. in a managerial, executive, or specialized knowledge role.⁶

There are two subcategories:

L-1A for managers and executives, up to seven years total.⁷
L-1B for specialized knowledge workers, up to five years total.⁷

“Specialized knowledge” for L-1B means expertise in the company’s products, services, processes, or techniques that goes beyond what a typical employee in that role would know and that is not readily available in the U.S. labor market. The bar is genuinely high, and USCIS denies a significant share of L-1B petitions for failing to prove it. Like the H-1B, the L-1 permits dual intent.

Canadian citizens can present L-1 documents at a CBP-designated port of entry rather than a consulate, though the employer still has to file Form I-129 with USCIS beforehand.⁸

O-1 for Extraordinary Ability

The O-1 is for individuals with sustained national or international acclaim in the sciences, business, education, athletics, or the arts. Your employer or agent files Form I-129 with an evidence package, and USCIS requires at least three different types of qualifying documentation, such as major awards, published material about your work, a high salary relative to peers, or evidence of a leading role in distinguished organizations.⁹

There is no annual cap and no lottery. If you genuinely qualify, the O-1 can be faster than the H-1B path, and it allows dual intent.

E-2 for Investors and Entrepreneurs

Because Canada has a treaty of commerce with the United States, Canadian citizens qualify for the E-2 visa. It is for individuals who invest a substantial amount of capital in a U.S. business and plan to develop and direct that enterprise. You must own at least 50% of the business or have operational control through a managerial position.¹⁰

There is no fixed dollar minimum for “substantial.” The investment has to be large enough relative to the total cost of the business to show real financial commitment. A $20,000 investment in a business worth $500,000 would not qualify; a $100,000 investment in a $150,000 business likely would. The E-2 is renewable indefinitely and has no annual cap, which makes it the standard option for Canadian entrepreneurs and small business owners locked out of TN by the self-employment rule.

Which Visa Fits Your Situation

The choice usually comes down to a few facts about your job:

If your profession is on the USMCA list and you have a U.S. employer, TN is the fastest and cheapest option.
If your job needs a specialty degree but is not on the TN list, or you want to pursue a green card openly, H-1B is the default path, subject to the lottery.
If you already work for a multinational with a U.S. office, L-1 skips the lottery and lets your spouse work.
If you have documented top-tier achievements, O-1 avoids the cap entirely.
If you want to run your own U.S. business, E-2 is the option TN cannot give you.

Applying and Entering at the Border

You will need a Canadian passport that stays valid through your intended stay. Beyond that, the documents depend on the classification. For TN, bring a support letter from your employer describing the job duties, how they map to a USMCA-listed profession, the duration of employment, and your pay, along with original diplomas, transcripts, or licenses proving your credentials. For H-1B, L-1, and O-1, your employer files Form I-129 with USCIS first, and you bring the approval notice (Form I-797) to the port of entry.¹¹ For O-1, USCIS recommends filing at least 45 days before the employment start date.

TN status at a land port of entry costs $50 for the application plus $30 for the I-94 arrival record, totaling $80. The I-94 fee rose to $30 effective September 30, 2025. Employers can request premium processing on Form I-129 by filing Form I-907, which guarantees USCIS action within 15 business days.¹² As of March 1, 2026, the premium processing fee for Form I-129 is $2,965.¹³ Without premium processing, standard times can stretch several months depending on the service center and classification.

For TN and L-1, Canadians apply at a CBP-designated port of entry or pre-clearance facility rather than at a consulate.⁸ The officer conducts an interview and makes the decision on the spot for TN. For H-1B and O-1, the officer verifies your documents against the already-approved petition.

After admission, CBP issues an I-94 documenting your class of admission and the date your stay expires. Air and sea entries generate electronic records you can retrieve at i94.cbp.dhs.gov using your name, date of birth, and passport information.¹⁴ Land border entries may produce a paper form. Check it immediately. Errors on the I-94 cause real problems with employers and future entries.

A TN denial at the border does not automatically bar you from the United States, but the consequences depend on the reason. A denial based on insufficient qualifications generally results in heightened scrutiny at future entries. A denial based on unlawful presence can trigger a three- or ten-year bar. A denial involving fraud can result in a permanent bar. The denial goes on your record and every CBP port of entry can see it, so returning the next day with the same documents to try a different officer is not a viable strategy.

Bringing Your Family

Your spouse and unmarried children under 21 can come with you, but whether your spouse can work depends on which visa you hold.

TN dependents (TD status) can live in the U.S. but cannot work. No employment authorization is available.
L-1 dependents (L-2 status) can work automatically. Since January 2022, CBP issues an I-94 with the code “L-2S” that itself serves as proof of employment authorization for Form I-9 purposes.¹⁵
H-1B dependents (H-4 status) can apply for work authorization, but only if the H-1B holder is the beneficiary of an approved I-140 immigrant petition or qualifies under the American Competitiveness in the Twenty-first Century Act. Without an approved I-140, H-4 spouses cannot work.¹⁶

If your spouse’s income is part of the plan, L-1 is the cleanest option. TN holders whose spouses need to work often look at whether the spouse independently qualifies for their own TN or H-1B.

If You Want a Green Card Later

H-1B and L-1 both allow dual intent. Your employer can file an I-140 immigrant petition while you keep working, and USCIS will not treat that as a reason to deny an extension.

TN is different. It is not a dual-intent classification, so you must maintain the intent to return to Canada. Filing an I-485 adjustment of status application can be treated as evidence that you intend to stay permanently, which can jeopardize your TN status and complicate re-entry if you travel. Many immigration attorneys advise TN holders to move to H-1B before starting the green card process, or to use consular processing (applying for the immigrant visa at a U.S. consulate abroad) to avoid the dual-intent problem while still in TN status. Mistakes at this stage are expensive.

Tax Obligations Canadians Often Miss

Working in the U.S. on any visa triggers U.S. tax obligations that catch many Canadians off guard. You will need a Social Security Number, and you may owe taxes to both countries at once.

The IRS uses the substantial presence test to decide whether you are a U.S. tax resident. You meet it if you are physically present in the U.S. for at least 31 days in the current year and 183 days across 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 in the year before that.¹⁷ Most full-time workers hit it within a year or two. Once you qualify as a U.S. tax resident, you owe federal income tax on your worldwide income. The U.S.-Canada tax treaty has tie-breaker rules to prevent true double taxation when both countries claim you.

If you keep Canadian bank accounts, retirement accounts, or other financial accounts, you may have a reporting obligation most people do not expect. Any U.S. person with foreign financial accounts whose combined value exceeds $10,000 at any point during the year must file a Report of Foreign Bank and Financial Accounts (FBAR) with the Financial Crimes Enforcement Network.¹⁸ The threshold is aggregate across all accounts. Penalties for non-filing can be severe.

You and your employer will also pay into Social Security and Medicare. The U.S.-Canada Totalization Agreement ensures that years worked in Canada under the Canada Pension Plan can count toward U.S. Social Security eligibility, and vice versa.¹⁹ U.S. retirement benefits generally require at least 10 years of work credits, and splitting a career across the two countries can leave you short in both systems without the agreement.

To get a Social Security Number, visit a Social Security Administration office in person with your passport and I-94 record. The previous requirement to wait 10 days after entry has been eliminated.
