If you’re currently working in the U.S. under a TN visa, it’s essential to understand the TN visa renewal process before your status expires. Whether you’re renewing for the first time or the fifth, this guide breaks down everything you need to know—from required documents and timeline to renewal methods and denial tips—in simple, understandable language.
This guide provides a clear, step-by-step breakdown of everything you need to know—from eligibility and required documents to renewal methods, timelines, and what to do if your application is denied. Let’s get right into it.
What Is the TN Visa and Why Renewal Matters
The TN (Trade NAFTA) visa allows Canadian and Mexican professionals to work in the U.S. under the United States-Mexico-Canada Agreement (USMCA). It’s a nonimmigrant work visa for certain eligible professions—like engineers, scientists, accountants, teachers, and more.
Unlike H-1B visas, TN visas don’t require a petition lottery or long waiting periods. But there’s a catch; they are typically issued for up to three years and must be renewed before they expire. That’s where this guide comes in.
Who Can Renew a TN Visa in 2025?
If you’re a Canadian or Mexican citizen already in the U.S. on a TN visa and you’re continuing in the same job role with the same employer, you’re generally eligible to renew your TN visa. Renewal is allowed multiple times, and there is no hard limit on how many times you can renew—so long as you continue to prove that your intent is temporary and non-immigrant in nature.
Even your spouse and children on TD visas can renew their status alongside you.
How to Renew TN Visa in 2025: Step-by-Step
One of the most common questions we get is: how do I renew my TN visa before it expires?
The good news is that you have options.
There are three main ways to renew a TN visa:
1. Renew TN Visa by Mail (Using Form I-129)
This is the most common method for renewing from within the U.S. If you’re not traveling soon and want to avoid border wait times, this might be your best option.
Your employer files Form I-129 with USCIS. Once approved, you’ll receive a new I-94 without leaving the country.
Processing time takes about 2–6 months and 15–45 days with Premium Processing.
2. Renew TN Visa at the U.S. Border or Port of Entry (Canadians Only)
If you’re a Canadian citizen, you can exit and re-enter the U.S. to renew your TN visa at the land border or airport. This method offers faster results, but you’ll need all your documents ready.
Processing Time is usually Immediate, upon inspection.
3. Renew TN Visa at a U.S. Consulate (Mexican Citizens)
Mexican citizens must attend a visa appointment at a U.S. consulate abroad. This option is best if you’re traveling internationally or need to update visa documentation in your passport.
Processing Time varies by consulate, but it usually takes 7–21 days.
TN Visa Renewal Requirements: What You Need in 2025
To successfully renew your TN visa, you’ll need to provide a complete and updated application package. Here are the core TN visa renewal documents:
- Letter from your employer confirming continued employment, job duties, salary, and TN-eligible profession
- Proof of professional qualifications (e.g., degree certificates, licenses)
- Valid passport
- Current I-94 record or previous approval notice
- Form I-129 (if renewing by mail)
- Optional but helpful: A TN visa renewal letter sample to format your employer’s letter correctly
It is important to note that a weak or generic employer letter is one of the top reasons why TN visa renewal is denied. Be sure yours includes all the right details.
TN Visa Renewal Processing Time: What to Expect
Processing time depends on the method you choose:
- Mail (Form I-129): 2–6 months
- Premium Processing (USCIS): 15–45 days
- Border (Canadians): Same-day result
- Consulate (Mexicans): Usually 7–21 business days
So, can you renew your TN visa before it expires?
Yes, and you absolutely should. USCIS recommends applying at least 45–90 days before your current visa expires to avoid gaps in employment.
Can You Renew a TN Visa Multiple Times?
Yes, you can renew your TN visa multiple times. There is no set maximum number of renewals. However, TN status is only valid for individuals who intend to remain in the U.S. temporarily. If you’ve renewed several times, immigration officers may start questioning whether your stay is truly temporary.
To avoid suspicion:
- Maintain a home abroad
- Avoid filing for green card status while on TN
- Be consistent in your job role and purpose of stay
What If Your TN Visa Renewal Is Denied?
Denials can happen, and they often come down to one of these issues:
- Incomplete or unclear employer letter
- Job duties don’t match the approved TN category
- Insufficient qualifications
- Change in job/employer not properly documented
- You’ve shown intent to immigrate permanently
If your TN visa renewal is denied, you may be asked to leave the U.S. immediately or reapply at a consulate. Always review denial reasoning carefully and consult an immigration attorney for help with reapplication or appeals.
Conclusion: Prepare Early, Renew Confidently
