TN Visa Requirements: What You Need to Qualify

A TN visa, more precisely "TN status," lets Canadian and Mexican citizens work temporarily in the United States in one of a defined list of professional occupations. The category comes from the United States-Mexico-Canada Agreement (USMCA), the trade agreement that replaced NAFTA in 2020. USCIS still calls the category "TN," the designation that originated under NAFTA, and both terms get used interchangeably in practice.

Unlike the H-1B, there's no lottery and no annual cap. For Canadian citizens, there's often no visa stamp at all: CBP can process many applicants directly at a land border crossing or an airport preclearance station. That speed is exactly why TN status gets mistaken for simple. The occupation list and the supporting paperwork are strict, and a job title that's "close enough" to the list is where most denials happen.

Job-title mismatches like this show up across occupations, not just in tech. Paramedics and EMTs are a common example: the job offer is real and the employer is willing to sponsor it, but "Paramedic" and "EMT" simply aren't occupations on the USMCA list, no matter how the position is described. Attorneys who work with Marble Law typically map a client's actual day-to-day duties against the listed occupations before filing, and when there's no reasonable match, the honest answer is that TN status isn't available for that role, even if a different visa category might be.

This list is not exhaustive, and USCIS and CBP periodically clarify how specific job titles map to it. If your offered title doesn't appear verbatim, that doesn't automatically disqualify you. But it does mean the job duties, not just the title, need to clearly match a listed category.

This is where TN status diverges sharply by citizenship, and it's the step where most avoidable mistakes happen.

Canadian citizens generally don't need a visa stamp in advance. You can apply directly at a U.S. land port of entry, an airport with U.S. preclearance, or a key port of entry, presenting your documents to a CBP officer, who adjudicates the case on the spot.

Mexican citizens generally need a TN visa issued by a U.S. consulate before traveling. That means filing Form DS-160, paying the visa application fee, and attending a consular interview. Only after the visa is issued can you present yourself at a port of entry.

Either nationality can also have their employer file Form I-129 with USCIS on their behalf as an alternative route. Employers sometimes choose this if there's a prior denial, a complicated case, or a preference for a documented approval before travel.

Costs and timelines depend heavily on which route you use.

Canadian citizens applying at a land port of entry now pay a $30 Form I-94 fee, up from $6, after a fee increase that took effect September 30, 2025, under a federal statute known as HR-1. Processing at the border is often same-day, though wait times vary by port and time of year.

Mexican citizens generally pay the standard nonimmigrant visa application (MRV) fee, which the State Department sets for most visa categories. Add the cost and wait time for a consular appointment, and this route can take several weeks longer than the Canadian port-of-entry route.

If your employer files Form I-129 with USCIS instead, that route carries its own filing fee, and USCIS's premium processing option (for an additional fee) can bring a decision in as little as a few weeks. Because government fees change, confirm current amounts directly on USCIS's fee schedule before budgeting for either route.

Marble Law's own case data reflects this split. Of 61 single-service TN matters on record for Canadian and Mexican professionals, 41 (67%) went through the Canadian port-of-entry route, well ahead of the 12 (20%) filed as USCIS I-129 petitions and the 8 (13%) filed through Mexican consular processing (DS-160). In other words, when clients qualify for the direct border route, they typically use it.

The biggest practical difference is availability. The H-1B has an annual cap and a lottery. TN status doesn't. If you qualify, you qualify every year, with no randomness involved.

The trade-off is scope. TN status only covers the USMCA profession list and only for Canadian and Mexican citizens. The H-1B, O-1, and other work visa categories are open to any nationality and cover a much broader range of occupations.

TN status is also explicitly not a "dual intent" visa the way the H-1B is. You generally need to maintain ties showing you intend to return home. Taking steps toward permanent U.S. residence while on TN status can create real complications, and this is a common area where generic advice, like "just adjust status later," causes problems in practice.

TN status can be renewed indefinitely, in increments of up to three years each time, as long as you continue to meet the same requirements: citizenship, a qualifying profession, a valid job offer, and temporary intent.

Getting a green card from TN status is possible, but it isn't automatic and isn't handled through the TN process itself. Because TN status isn't dual intent, most people pursue a green card through a separate pathway, commonly an employer-sponsored PERM labor certification followed by an immigrant visa petition. USCIS generally expects you to resolve the tension between TN's temporary-intent requirement and taking concrete steps toward a green card. This is worth raising with an immigration attorney well before you start that process, not after.

TN status is federal, so it doesn't change from state to state the way family law does. What it does change on is citizenship. The requirements below apply nationwide, but which one applies to you depends entirely on whether you're Canadian or Mexican.

Canadian citizens: Apply directly at a port of entry, preclearance site, or land border crossing. No advance visa stamp is required in most cases. A CBP officer adjudicates on the spot.

Mexican citizens: Must obtain a TN visa stamp from a U.S. consulate first, via Form DS-160 and a consular interview, before presenting at a port of entry.

Canadian or Mexican permanent residents who are not citizens: Do not qualify for TN status at all, regardless of how long they've held residency.

Note: these categories reflect the standard process as of this writing. Consult an immigration attorney to confirm current procedures, since consular and CBP practices can shift.

An immigration attorney reviewing a TN case typically does more than check a box on your job title. Attorneys compare your actual job duties, not just the title your employer used in the offer letter, against the USMCA occupation list. They also help rewrite ambiguous job descriptions before you ever present them at the border or consulate.

Beyond that, attorneys review your credentials for an exact match to what the occupation requires, and flag prior visa denials or overstays that could complicate a new application. They can also advise on the practical tradeoff between applying at the border and having your employer file Form I-129 with USCIS in advance.

For Mexican applicants, an attorney can also help prepare for the consular interview itself, since a DS-160 application and interview carry different risks than a CBP port-of-entry encounter.

Applying for a TN visa? An immigration attorney who works with Marble Law can review your job offer and documentation before you file. If your situation involves a different work visa category, they can help you find the right one.

TN status can be one of the fastest ways for a Canadian or Mexican professional to start working legally in the U.S. But "fast" only holds up if your occupation, credentials, and paperwork line up with the USMCA list before you get to the border or the consulate. Getting the TN visa requirements right the first time avoids the alternative: a denial that can delay your start date by weeks or longer.
