- CBP continues processing TN category changes and employer switches at ports of entry during the shutdown.
- The Department of Labor pause blocks new H-1B filings due to LCA system offline status.
- Increased vetting and tighter documentation are causing significant delays and more secondary inspections at borders.
(UNITED STATES) A 45-day Department of Homeland Security shutdown is slowing many immigration services, but CBP continues to process TN category changes and employer switches at the border. USCIS remains open for fee-funded filings inside the United States, while the Department of Labor pause blocks LCAs and H-1B petitions but leaves TN border processing intact.
That split matters for Canadian and Mexican professionals, employers, and families planning U.S. starts this spring. It also matters because enhanced vetting, expanded travel screening, and tighter documentation checks are adding more time at ports of entry. For official traveler guidance, CBP posts updates on its website for border operations and travel notices.
Border Processing Still Works, But It Is Slower
CBP treats inspections and admissions as essential work, so officers stay on duty during a funding lapse. That means TN filings at land borders and airports remain available, including changes of employer and changes of TN category. Canadian nationals seeking initial blanket L status at designated ports also continue to be processed.
The practical reality is more complicated. A shutdown does not close the border, but it does stretch wait times. Officers face staffing pressure, longer lines, and more secondary inspections. The current shutdown has already reached 45 days, the longest in U.S. history, and that adds uncertainty to every port interaction.
For many applicants, that means a same-day answer is still possible, but not guaranteed. A case that once took an hour can take much longer when officers are working through added vetting and crowded inspection lines. VisaVerge.com reports that the pattern is clear: border work continues, yet the pace slows when federal funding disappears.
USCIS, Department of Labor, and Why TN Avoids the LCA Problem
USCIS is fee-funded, so it stays open during a shutdown. It continues to handle extensions and changes of status filed inside the United States. That does not help at the border, because USCIS does not adjudicate TN cases presented to CBP at a port of entry.
The Department of Labor is different. Its shutdown pause takes the Labor Condition Application system offline and blocks new H-1B filings. TN processing does not use an LCA. That is why TN remains available even while the H-1B route stalls.
For employers, that difference is now central to hiring plans. A role that might have gone through H-1B filing may be faster through TN if the job fits a USMCA profession. The shutdown has made that choice more important, especially when a start date is fixed and a worker is already eligible for TN classification.
Enhanced Vetting Is Adding New Friction at Ports of Entry
The shutdown is not the only force shaping border processing. In December 2025, USCIS created a Vetting Center to centralize enhanced screening for security, fraud, and criminal concerns. The Trump Administration also expanded social media and online presence checks. Those steps affect immigration processing more broadly and are now part of the atmosphere around TN adjudications.
At the border, that means CBP officers can ask more detailed questions about the job, the degree, the duties, and the applicant’s travel and online history. Officers may also send more people to secondary inspection. Some ports may apply those checks more aggressively than others, which is why the same file can move quickly in one city and slowly in another.
Applicants should expect closer review of their professional story. A bare job title is not enough. Officers want to see a clear match between the duties and a listed TN profession. That is where precise paperwork matters most.
What Applicants Need Before They Cross
- Job letter with duties, start date, salary, and the exact TN category
- Proof of qualifications, such as degrees, licenses, or certifications
- Job description or contract showing how the role fits the TN profession
- Employer letterhead and contact details for quick verification
- Passport and travel documents
- Proof of Canadian or Mexican nationality
- Past TN approvals if you have held TN status before
A strong letter helps more than a long one. It should name the profession, explain the duties, and avoid vague wording. If the position is for a Computer Systems Analyst or Management Consultant, say so directly. If the applicant is changing employers, the new role should be described with the same level of care.
Bring backup copies. Carry documents in paper form, not only on a phone. If CBP asks for more proof, quick access matters.
Travel Planning During the 45-Day Shutdown
Timing now matters more than usual. Long weekends, Friday afternoons, and the busiest commuter hours create the most risk. Many crossings are heaviest between 7-9 AM and 4-6 PM. For applicants with fixed start dates, arriving early in the day reduces pressure and gives more room for follow-up questions.
Border crossings are still possible, but patience is part of the plan. Build in at least two to three hours of extra time. If the case moves to secondary inspection, the wait can stretch much longer. Families should plan for that too. Delays can affect school drop-offs, childcare, hotel bookings, and employer onboarding.
Employers should also keep schedules flexible. A worker who expects to cross before noon may not finish until late in the day. A soft start date reduces panic. Clear communication between HR, managers, and the worker avoids confusion when the port is slower than expected.
Why Employers Are Relying More on TN Right Now
The Department of Labor pause has made TN more attractive for roles that fit the treaty list. H-1B employers cannot move forward without LCAs, but TN remains available at the border because it follows a different legal path. That difference is now shaping hiring across sectors that depend on cross-border talent.
HR teams should prepare detailed letters, confirm the exact job category, and make sure the employee understands the duties before travel. They should also expect longer processing times and possible secondary inspection. A flexible hiring calendar is no longer a nice extra. It is part of the immigration plan.
The wider policy climate adds another layer. Expanded travel restrictions and tighter documentary review are already affecting how border officers assess applicants. While these changes have been aimed mainly at other visa categories, they send a clear signal: scrutiny is higher, and preparation matters more than ever.
Why the Shutdown Has Not Stopped TN, and What Comes Next
The legal reason TN continues is straightforward. CBP border inspections are essential. USCIS fee-funded work continues. The Department of Labor pause blocks H-1B filing, not TN admissions. That three-way split is why a shutdown slows the system without stopping every path at once.
The politics around the shutdown remain unresolved. House Republicans rejected a Senate-passed solution, and lawmakers are discussing a two-step plan with a target resolution date of June 1. Until that happens, border processing remains open but uneven. Some ports will move cases faster than others. Some will ask more questions. Some will send more people to secondary inspection.
The same caution applies to related immigration settings. Consular services may scale back to emergency-only work, and that may push more Canadian professionals toward the border route. For now, TN remains one of the few work pathways that still operates at the front line, even as the broader immigration system absorbs the shock of a long shutdown.
CBP’s role keeps that channel open. USCIS keeps its fee-funded system moving inside the country. The Department of Labor stays offline for key employer filings. That is the landscape as April 2026 unfolds, and it is the reason every TN applicant now needs stronger paperwork, more patience, and a lot more time at the border.
