Derry TN Visa Lawyer

A TN visa connects your professional future to a single document, a single filing, and a single decision made by an immigration officer who does not know you. For Canadian and Mexican professionals working or hoping to work in Derry, New Hampshire, the TN visa category under the United States-Mexico-Canada Agreement offers a direct path to lawful employment in the United States. But that path is narrower than it appears. The eligibility criteria are specific, the qualifying occupations are fixed, and the documentation standards are unforgiving. When the details are right, TN status can be approved at the border in a matter of hours. When they are not, the consequences ripple outward into every area of your life. Working with a Derry TN visa lawyer who prepares these filings with the discipline they require is not a precaution. It is the difference between moving forward and starting over.

What the TN Visa Actually Requires and Why Details Matter

The TN nonimmigrant classification was created under NAFTA and preserved under USMCA specifically for citizens of Canada and Mexico who qualify for one of a defined list of professional occupations. The list includes engineers, accountants, scientists, computer systems analysts, lawyers, pharmacists, physical therapists, and several dozen other categories. The occupation must match both the job offer and the applicant’s credentials. A mismatch between job title, degree, and duties is one of the most common reasons TN admissions are denied or RFEs are issued, and the consequences of that mismatch are not administrative inconveniences. They can mean delayed employment, disrupted relocation plans, and in some cases, a flag on future admissions that follows a professional for years.

Canadian citizens applying at a port of entry have the procedural advantage of seeking TN admission directly at the border without a prior visa. That speed is appealing, but it creates a false sense of simplicity. The customs and border protection officer at the port of entry has full discretion over the admission decision, and an incomplete or poorly organized documentation package can result in a denial on the spot. Mexican nationals face an additional step, requiring a TN visa stamp at a U.S. consulate before admission. In either case, what protects the applicant is not enthusiasm or confidence. It is a file that has been built to withstand skeptical review before the professional ever reaches the inspection booth.

Attorney Jason M. Sullivan has concentrated exclusively on U.S. immigration law for more than two decades. His practice is built around the understanding that the quality of the initial filing determines how smoothly a case moves, and TN matters are no exception. The Law Office of Jason M. Sullivan, PLLC prepares TN petitions and supporting documentation with the same precision applied to complex green card and employment-based immigrant visa cases, because the professional standing at a border or waiting for an approval notice deserves that level of care.

The Stakes When TN Status Goes Wrong

TN visa errors are rarely isolated. They tend to compound. A professional who enters in the wrong classification, or who fails to properly extend status before the authorized period expires, may find themselves in a period of unlawful presence without realizing it. Under federal immigration law, accruing more than 180 days of unlawful presence triggers a three-year bar on reentry. More than one year triggers a ten-year bar. These are not theoretical consequences. They are statutory provisions that have ended or severely disrupted the U.S. careers and family arrangements of professionals who assumed their status was fine.

Employment authorization is equally at risk. A TN professional whose status lapses even briefly may be prohibited from working legally in the United States. For employers, that creates liability concerns and operational disruptions. For the professional, it means lost income, potentially lost job offers, and in some industries, a professional record that reflects an unauthorized employment period. The financial and reputational costs of a status problem almost always exceed what it would have cost to do the filing correctly in the first place.

There is also the family dimension. Many TN visa holders bring spouses and dependent children to the United States under TD nonimmigrant status. A defect in the TN principal’s status can affect TD dependents as well, creating a situation where the entire family’s ability to remain in the United States is tied to whether a single petition was properly prepared. That weight is real, and it should inform how seriously a TN matter is treated from the very beginning.

TN Visa Extensions, Employer Changes, and Long-Term Planning

TN status is initially granted for up to three years and can be extended in additional three-year increments without statutory limit. That flexibility makes the TN category attractive to professionals who want to build their careers in the United States over an extended period. But indefinite TN renewals carry their own complexities, particularly for professionals who may eventually seek permanent residence. Unlike certain other nonimmigrant categories, TN status does not fit neatly into a pathway toward a green card. Maintaining TN status while simultaneously pursuing an immigrant intent can create legal tensions that require careful management.

Changing employers also requires attention. Unlike some visa categories, a TN holder who moves to a new employer cannot simply start work and notify USCIS later. The new employment must be authorized before it begins, either through a new admission at a port of entry or through a properly filed petition with USCIS. Getting this wrong is a common source of status problems, particularly for professionals who are recruited quickly or who assume that the flexibility of TN status extends to informal employer transitions.

For professionals who ultimately want permanent residence in the United States, planning ahead matters. Attorney Sullivan handles employment-based immigrant petitions, including EB-2 National Interest Waivers and PERM labor certification, and understands how to structure a long-term immigration strategy that accounts for what comes after TN status. That forward-looking perspective is part of what distinguishes careful representation from simple form preparation.

Derry TN Visa FAQs

Who qualifies for TN visa status?

TN status is available to citizens of Canada and Mexico who are entering the United States to work in a qualifying professional occupation listed under USMCA. The applicant must have a job offer from a U.S. employer, and both the position and the applicant’s credentials must match the qualifying occupation category. A relevant academic degree or professional credential is typically required, though specific credential requirements vary by occupation.

Can a TN visa holder apply for a green card?

Technically, yes, but the situation requires careful management. TN status is a nonimmigrant classification, meaning it is premised on a temporary intent to remain in the United States. Pursuing permanent residence while in TN status can create issues related to immigrant intent. Working with an attorney who understands both TN status and employment-based immigrant pathways is essential for professionals who want to transition from temporary to permanent status without disrupting their current authorization.

What documents are needed for a TN admission?

A Canadian citizen applying at the border generally needs a valid passport, a detailed support letter from the U.S. employer describing the position, duties, and compensation, and evidence of qualifying credentials such as a degree or professional license. Mexican nationals additionally need a TN visa obtained through the U.S. consulate prior to travel. The completeness and organization of the documentation package significantly affects the outcome of the admission process.

How long does TN status last and how is it renewed?

TN status is granted for periods of up to three years. It can be renewed in additional three-year increments either through a new admission at a port of entry or by filing a petition with USCIS. There is no statutory limit on the number of times TN status can be renewed, but each renewal requires a continuing valid job offer and confirmation that the professional still meets the qualifying occupation criteria.

What happens if a TN holder changes jobs?

A TN visa holder must secure authorization under the new employment before beginning work for the new employer. This can be accomplished by obtaining a new TN admission at a port of entry or by filing a change of employer petition with USCIS. Working for a new employer without first securing proper authorization is a status violation that can have serious long-term immigration consequences.

Does the Law Office of Jason M. Sullivan handle both TN visa applications and extensions?

Yes. The firm represents professionals in initial TN admissions, TN extensions through USCIS, and employer change situations. For professionals with longer-term goals, Attorney Sullivan also handles employment-based immigrant visa matters including EB-2 National Interest Waivers and employer-sponsored petitions, allowing for a coordinated strategy that accounts for both current status and future immigration objectives.
