San Diego TN Visa Attorney

A U.S. Job Offer Is the Starting Point. A Solid Application Gets You Through the Door.

For Canadian and Mexican professionals with a qualifying job offer, the TN visa is one of the fastest routes to working legally in the United States. The structure is efficient — but the documentation has to be airtight. A U.S. Customs and Border Protection (CBP) officer at the border or a consular officer in Mexico decides on the spot, and there is no appeal window if the application falls short.

San Diego Immigration Law Office prepares TN applications built to clear that bar. Attorney Ricardo Elorza works with professionals and U.S. employers throughout San Diego to ensure everything is correctly categorized, credentialed, and documented before it ever reaches the inspection window.

Canadian vs. Mexican Applicants: Two Different Processes

The mechanics of applying differ significantly depending on whether the applicant is a Canadian or Mexican citizen, and understanding that difference upfront avoids surprises.

Canadian citizens (TN-1) 

Canadian citizens do not need to obtain a TN visa stamp at a consulate before traveling. They may apply for TN admission directly at a CBP-designated U.S. port of entry or a pre-clearance station by presenting the required documentation to a CBP officer. If the officer finds the applicant eligible, TN status is granted on the spot. Canadians already in the United States in lawful nonimmigrant status can also request a change of status or extension through USCIS using Form I-129, without leaving the country.

Mexican citizens (TN-2)

Mexican citizens must obtain a TN visa stamp at a U.S. embassy or consulate in Mexico before traveling to the United States. The consular application requires a personal interview and full documentation review. Once a TN visa is issued, the holder may apply for admission at a CBP-designated port of entry, where the period of admission is determined.

For both groups, the quality and completeness of the supporting documentation drives the outcome. Attorney Elorza prepares clients and their employers for both pathways, with materials built to the standard each process demands.

Which Professions Qualify?

The USMCA profession list covers numerous occupations across a range of fields. The categories most commonly seen in TN applications include:

• Engineering: Civil, mechanical, electrical, chemical, industrial, and computer engineering roles
• Information technology: Computer systems analysts and computer programmers (note that modern titles like software engineer or software developer must map clearly to a listed USMCA category)
• Healthcare: Registered nurses, dentists, pharmacists, physicians (with specific restrictions on patient care roles), dietitians, and medical laboratory technologists
• Sciences: Biologists, chemists, geologists, physicists, and scientific technicians working in support of a supervisory professional
• Business and finance: Accountants, economists, and management consultants
• Education: College and university teachers, librarians, and researchers
• Other: Architects, graphic designers, hotel managers, land surveyors, lawyers, and range managers, among others

Job title and job duties are not the same thing. A person with the title "Software Engineer" may qualify under the "Computer Programmer" category if their actual duties align with that classification and the employer letter frames the role correctly. Conversely, a title that appears to match a listed profession does not guarantee eligibility if the duties or credentials fall short. This gap between title and duty is where many TN applications run into problems, and it is where careful preparation with an attorney makes a meaningful difference.

At San Diego Immigration Law Office, we analyze both sides of that question before a single document is assembled: does the role genuinely qualify, and is the application positioned to demonstrate that clearly?

What Makes a TN Application Strong

The documentation a TN applicant brings to the port of entry or submits to the consulate is the entire case. There is no follow-up brief or second hearing. The most common reasons TN applications are refused come down to preventable preparation failures:

• An employer support letter that describes the job title but not the specific professional duties, or that fails to connect those duties to the qualifying USMCA category
• Credentials that are not clearly translated, evaluated, or explained in relation to U.S. equivalency standards
• A profession category that does not match the duties actually being performed
• Missing documentation for professions that require licensure in addition to a degree, such as architects and engineers in some states
• Applications for professions with stricter post-2025 USCIS guidance, such as certain healthcare and scientific roles, that do not account for the updated standards

San Diego Immigration Law Office drafts employer support letters that go beyond a summary of job responsibilities. We build the connection between the role, the USMCA category, the applicant's credentials, and the legal standard the reviewing officer will apply. That level of preparation is what separates an application that moves through from one that gets flagged at the inspection window.
