One of the most common compliance questions we hear from brokers entering the cross-border market: “If the carrier’s drivers are employed by a Mexican company, how do I vet them?” Here’s the straightforward answer.
What Is a B-1 Driver?
A B-1 driver is a Mexican national with a B-1 business visitor visa who is authorized by U.S. Customs and Border Protection (CBP) to haul freight across the U.S.-Mexico border.
What they can do:
- Move any load that crosses an international border — for example, Monterrey to Chicago, or Dallas to Monterrey
- Pick up a return load in the U.S. as long as that freight is destined for Mexico
What they cannot do:
- Move domestic U.S. freight — for example, Dallas to Houston. That’s called cabotage, and it’s illegal under federal law.
It’s really that simple: B-1 drivers are only allowed to move international shipments.
The B-1 visa is not a “worker visa.” It’s a business visitor visa that allows foreign nationals to conduct certain types of business in the United States. For trucking, it permits drivers from Mexico to enter the U.S. for one purpose: to haul freight that crosses an international border. — CBP
Who Do You Actually Book?
You book a U.S.-based carrier with a DOT# and MC#, just like any other carrier. The difference is that their drivers are Mexican nationals — typically living in border cities like Nuevo Laredo — who cross into the U.S. on B-1 visas to pick up and deliver international freight.
From the broker’s perspective, this carrier looks and operates like any other U.S. carrier. They hold U.S. operating authority, carry U.S. insurance, and are fully responsible for the load.
Why Is the Driver Paid Through a Mexican Company?
This is the part that trips people up, but it’s straightforward once you understand the visa.
Because a B-1 is a visitor visa, not a work visa, the driver can’t legally be on a U.S. payroll. So the carrier pays its B-1 drivers through a Mexican payroll entity. This isn’t a subcontractor relationship but simply how the payroll is structured to stay compliant with U.S. immigration law.
The U.S. carrier still:
- Holds the operating authority (DOT# and MC#)
- Carries the insurance
- Dispatches the driver
- Is fully responsible for the load
Think of it this way: the broker books a U.S. carrier. That carrier’s drivers happen to live across the border and cross into the U.S. with B-1 visas. Their paychecks go through a Mexican entity because U.S. employment law doesn’t allow a B-1 holder to be on a W-2. That’s it.
How Do You Vet the Carrier?
The same way you vet any U.S. carrier. There’s nothing extra you need to verify about B-1 drivers specifically.
✅ Carrier-vetting Checklist:
- Active DOT# and MC# — Verify on FMCSA SAFER
- BIPD insurance — $750K minimum on file with FMCSA
- Cargo insurance — $100K+ recommended
- Safety rating — Satisfactory or Not Rated
- Confirm the load is cross-border — The shipment must originate or terminate outside the U.S.
Individual drivers are not listed on a carrier’s operating authority or insurance certificate — that’s true for all carriers, not just those with B-1 drivers. The carrier is responsible for ensuring its drivers are properly qualified and documented.
What About Cabotage?
This is where compliance teams should focus their attention. The legal risk isn’t the B-1 visa itself. It’s when drivers (or carriers) break the rules by hauling domestic-only freight.
Legal: Monterrey → Chicago (international, cross-border)
Legal: Chicago → Laredo, where the freight is destined for Mexico (international, export)
Illegal: Chicago → San Antonio, domestic freight with no international origin or destination (cabotage)
As a broker, the best way to protect yourself is to confirm the load you’re tendering is genuinely cross-border. If it is, B-1 drivers are fully authorized to move it.
The Bottom Line
Carriers with B-1 drivers are U.S.-registered, U.S.-insured, and operate under U.S. authority. The Mexican payroll entity exists because immigration law requires it, not because the carrier is cutting corners. In fact, carriers who are set up this way are demonstrating that they understand the rules and are structured to follow them.
The vetting process is the same as any other carrier. The only additional step is confirming the freight is international.
