If you’re a Canadian or Mexican professional planning to work in the U.S. under a TN visa, one of the most important things you’ll need to consider is the TN visa processing time. Whether you’re applying for the first time, extending your stay, or trying to speed things up with premium processing, understanding the timelines can help you avoid delays and plan your next move with confidence.
In this blog, we break down the processing time for TN visas, including regular, extension, and premium options, so you know what to expect every step of the way.
What Is the TN Visa and Why Is Processing Time Important?
The TN visa (short for Treaty NAFTA visa, now under USMCA) allows qualified Canadian and Mexican citizens to work in the U.S. in specific professional occupations such as engineers, accountants, scientists, and teachers. It’s one of the fastest and most accessible non-immigrant visa options for eligible professionals.
However, processing time can vary depending on:
- Whether you’re applying from within or outside the U.S.
- Whether you’re applying for a new visa or renewing one
- Whether you choose premium processing for faster approval
Knowing how long your application might take can help you avoid missed job start dates, legal stay issues, or unnecessary stress.
TN Visa Processing Time: An Overview
So, how long does TN visa processing take?
The processing time for a TN visa depends on your citizenship, how you’re applying, and where you’re applying from. Here’s a simplified breakdown:
- For Canadian citizens applying at a U.S. border or airport:
You can get your TN visa approved on the same day, often within a few hours, as long as your documents are complete and accurate. - For Mexican citizens applying at a U.S. consulate:
Processing typically takes 1 to 4 weeks, depending on the availability of interview appointments and how fast the consulate works. - For applicants filing from inside the U.S. through USCIS (Form I-129):
Standard processing time ranges from 2 to 6 months. This applies to both new applications and extensions. - If using premium processing through USCIS:
You’ll get a decision within 15 calendar days—this option is available only for applications filed through USCIS, not at the border or consulate.
Now, let’s take a closer look at each option.
Regular TN Visa Processing Time
For Canadians applying at the border or airport:
This is often the fastest route. Canadian citizens can apply for a TN visa directly at a U.S. port of entry, such as an airport with U.S. preclearance or a land border. If all documents are in order, the TN visa is usually granted on the same day, often within a few hours.
Documents required typically include:
- Proof of Canadian citizenship
- Job offer letter detailing your TN-eligible position
- Evidence of your professional qualifications
- Support letter from the employer
For Mexicans applying at a U.S. consulate:
Mexican citizens need to schedule a visa interview at a U.S. embassy or consulate. This includes completing the DS-160 application form, paying the visa fee, and attending an interview. The processing time for TN visa in this case typically ranges from 1 to 4 weeks, depending on the consulate’s workload and available interview slots.
TN Visa Extension Processing Time
If you’re already in the U.S. on a TN visa and want to extend your stay, you have two main options:
1. Apply through USCIS (Form I-129)
This is the most common method for TN visa holders already in the U.S. The TN visa extension processing time through USCIS usually ranges from 2 to 6 months, depending on service center workloads and backlogs.
Unfortunately, you can’t travel outside the U.S. while your extension is pending, unless you abandon the petition and reapply at the border (for Canadians) or via consulate (for Mexicans).
2. Reapply at the border (for Canadians)
If you’re a Canadian TN holder, you can also renew your TN visa by exiting the U.S. and applying again at the border. This can result in same-day processing, but it requires another employer’s support letter and complete documentation.
TN Visa Premium Processing Time
One of the most asked questions is:
“Is premium processing available for TN visas?”
The answer to that is yes, but only if you’re applying through USCIS using Form I-129 (either for an initial visa from within the U.S. or for an extension).
With premium processing, you’ll receive a decision from USCIS within 15 calendar days. This service currently costs $2,805 (as of 2025). It’s often used when time is of the essence, especially if your current visa is about to expire or you have a job offer that starts soon.
When Is Premium Processing Worth It?
The premium processing is a great idea if;
- You need to start work urgently
- Your current TN visa is close to expiration
- You’re changing employers or filing an extension from inside the U.S.
- You don’t want to risk long processing delays from USCIS
However, premium processing is not available for Canadians applying at the border or for Mexicans applying through a consulate, it’s strictly a USCIS service.
TN Visa Processing Time Comparison Table
Here’s a quick breakdown of all options:
| Application Type | Method | Estimated Time | Premium Available? |

| First-Time – Canadian | U.S. border or airport | Same-day (few hours) | No |
| First-Time – Mexican | U.S. consulate | 1–4 weeks | No |
| From inside U.S. (Form I-129) | USCIS (mail) | 2–6 months | Yes |

| Extension – Both | USCIS | 2–6 months | Yes |
How to Avoid TN Visa Processing Delays
If you want your TN visa processing to go as smoothly as possible, here are some key tips:
- Apply early: Don’t wait until your current visa is close to expiring.
- Check all documentation: Incomplete applications cause delays.
- Use premium processing if time is critical.
- Stay informed: Monitor USCIS processing times for Form I-129 at your assigned service center.
- Work with an immigration attorney if your case is complex or urgent.
