It was a brisk Sunday morning. The office was buzzing-phones ringing, paralegals flipping through case files, and the rhythmic clatter of keyboards filling the air. John sat across from Jan, coffee in hand, reviewing a new TN visa case file that had just landed on his desk.
A Conversation Between Two Top Attorneys: John and Jan
John:
“Jan, I’ve got a TN visa case here for a Canadian software engineer. The client’s qualified, but if the support letter isn’t airtight, the border officer could scrutinize it.”
Jan:
“Exactly, John. That’s where our paralegals excel. They draft detailed TN support letters that leave no gaps-professional qualifications, job duties, employer details-everything is mapped out clearly.”
John:
“Do they align the job duties precisely with the TN category?”
Jan:
“Every time. For this case, they’ll highlight duties like ‘developing software solutions and performing systems analysis’—language straight from the TN criteria. It’s professional, specific, and officer-friendly.”
John:
“And the qualifications?”
Jan:
“They include the exact degree title-Bachelor’s in Computer Science’-and link it directly to the TN occupation. Plus, they add a concise company overview to confirm legitimacy and temporary employment terms.”
John:
“That’s why our approvals are so smooth. With paralegals handling these letters so efficiently, it saves us time and avoids RFEs.”
Jan:
“Exactly. Their standardized templates, job-duty libraries, and precision drafting make TN letters fast, clear, and bulletproof.”
Mastering TN Visa Support Letter Preparation
1. Gathering Complete Applicant & Employer Information
Paralegals collect essential data such as:
-
Applicant’s degree, certifications, and relevant experience
-
Employer details: name, address, industry, and contact
-
Job specifics: title, duties, salary, and temporary term
Example:
“For a TN Engineer, they obtain applicant’s Bachelor’s in Mechanical Engineering and a detailed job description matching official TN criteria.”
2. Drafting with TN-Aligned Language
Paralegals use language that mirrors USMCA/NAFTA occupation definitions—job duties that directly reflect the sanctioned professional title (e.g. “system analysis, software design, technical specifications”).
Example: TN Software Developer
“As a Software Developer, Mr. John Smith will be responsible for system analysis, software design, coding, testing, and creating technical specifications to meet project requirements in alignment with TN visa occupational definitions.”
3. Highlighting Qualifications Clearly
They link academic credentials and experience directly to the TN category
Example for Highlighting Qualifications Clearly:
“Master of Science in Computer Science, University of British Columbia (2020), with 2 years of experience in software development and systems analysis for enterprise-level applications.”
4. Reinforcing Employer Credibility
Paralegals add a concise company description and note the temporary nature of the role:
Example:
“GreenBuild Engineering, a U.S.-based construction and design firm with 150 employees, specializes in sustainable infrastructure projects. The company has offered Mr. Alex Carter a 2-year Civil Engineer contract, confirming the temporary nature of his employment under the TN visa category.”
5. Templates & Automation for Speed
By using ready-made templates and approved duty phrases, paralegals can prepare a quality TN support letter in less than an hour, saving time and staying compliant.
