On November 18, 2025, U.S. Customs and Border Protection officers at the Brownsville Port of Entry seized over $70,749 in unreported U.S. currency during an outbound inspection at the Gateway International Bridge. The seizure is one of dozens that CBP’s Brownsville office conducts each year — and it illustrates a pattern that catches many legitimate travelers off guard.
What Happened
A southbound vehicle was selected for a routine outbound inspection at the Gateway International Bridge. Using a combination of canine units and nonintrusive imaging technology, CBP officers discovered $70,749 in bulk cash hidden in the vehicle. The currency was seized on the spot and Homeland Security Investigations (HSI) opened a formal investigation. The driver faced potential criminal charges in addition to the civil forfeiture of the cash.
CBP did not release details about how the cash was concealed, but the involvement of a canine unit and imaging technology is consistent with how Brownsville officers typically detect hidden currency — particularly in outbound vehicle inspections, where cash is often found in door panels, under seats, inside spare tires, or within aftermarket compartments.
Why Brownsville Is a High-Enforcement Port for Currency
The Brownsville Port of Entry processes tens of thousands of vehicle crossings per week between Brownsville, Texas and Matamoros, Mexico. CBP’s Brownsville officers conduct both inbound and outbound enforcement operations — a distinction that surprises many travelers who assume currency enforcement only applies to people entering the United States.
Outbound enforcement is, in many respects, more active at Brownsville than inbound. Federal law requires reporting of currency over $10,000 in both directions, and CBP treats southbound bulk cash as a priority enforcement issue because large amounts of unreported cash leaving the U.S. toward Mexico are frequently associated with drug trafficking proceeds. This enforcement posture means that even travelers carrying legitimately earned money — family remittances, business proceeds, real estate transactions — can have their funds seized if they fail to file the required report.
This particular seizure followed another Brownsville seizure just days earlier, in which CBP officers seized a separate amount of unreported currency at the same crossing. Repeat enforcement actions at the same port within a short window are not unusual — Brownsville CBP publishes its seizure activity regularly on social media, and the volume of actions at this port is among the highest of any land crossing in the country.
Is It Illegal to Carry More Than $10,000 Across the Border?
No. There is no legal limit on how much currency you can carry across the U.S.-Mexico border in either direction. What the law requires is that you report amounts over $10,000 by filing FinCEN Form 105 — the Report of International Transportation of Currency or Monetary Instruments — at the time of crossing. The reporting requirement applies to cash, traveler’s checks, money orders, and bearer negotiable instruments.
Failing to report does not require intent to commit a crime. The violation is the failure to file the form, regardless of the source of the funds. However, the way the money is carried can affect how CBP classifies the violation:
- Failure to report (31 USC 5316) — The baseline violation. The most forgiving classification under CBP’s mitigation guidelines when the money has a legitimate source and intended use.
- Bulk cash smuggling (31 USC 5332) — Applies when CBP believes the currency was actively concealed to avoid the reporting requirement. The involvement of hidden compartments, wrapped bundles, or distributed concealment methods elevates a failure-to-report case to smuggling — which carries potential criminal prosecution and significantly less favorable mitigation terms.
- Structuring (31 USC 5324) — Applies when CBP believes currency was divided among people or trips specifically to stay under the $10,000 threshold. A federal offense regardless of whether any individual amount exceeded the limit.
In the November 18 seizure, the involvement of hidden cash and canine detection suggests CBP classified this as a bulk cash smuggling case rather than a simple failure to report — a distinction that significantly affects what recovery options are available to the person whose money was seized.
Can You Get Your Money Back?
Yes — but it is not automatic, and it requires acting quickly. After a seizure, CBP mails a formal Notice of Seizure to the address provided at the crossing. The notice includes an Election of Proceedings form that must be returned within 30 days from the date of the notice. Missing that deadline is treated as abandonment, and CBP proceeds with administrative forfeiture — the money is gone with no further recourse.
The three response options are an administrative petition, a CAFRA judicial claim, or an offer in compromise. In most cases, an administrative petition filed with CBP’s Fines, Penalties & Forfeitures office is the right first step. A well-prepared petition documents the legitimate source of the funds and their intended use, and presents the legal and factual case for return — working within CBP’s internal mitigation guidelines to achieve the best available outcome.
In bulk cash smuggling cases — where the cash was found concealed — the mitigation guidelines are less favorable than in simple failure-to-report cases. But recovery is still possible, particularly when strong documentation of source and intended use is presented and no other aggravating factors are present. Full recovery has been achieved in cases with more difficult facts than a first-time concealment situation.
What to Do If Your Cash Was Seized at Brownsville
If CBP seized your currency at the Gateway International Bridge, the Brownsville and Matamoros International Bridge, or any other Brownsville-area crossing, take these steps immediately:
- Do not make any additional statements to CBP or HSI. You have already been through the seizure. Anything further you say can be used in forfeiture proceedings and in any related criminal investigation. Decline to discuss the matter further and contact an attorney.
- Keep all documentation from the seizure. The custody receipt, any paperwork CBP gave you at the crossing, and any subsequent notices that arrive by mail are all important to your case.
- Start gathering evidence of legitimate source and intended use. Bank statements, tax returns, business records, contracts, invoices, or any other documents that explain where the money came from and what it was for. The sooner you start, the stronger your petition will be.
- Watch for the Notice of Seizure in the mail. It will arrive within a few weeks. The 30-day response window starts from the date on the notice, not the date you receive it. Do not wait until the last minute.
- Contact a customs attorney before responding. The Election of Proceedings form is one of the most consequential documents in the entire process. Choosing the wrong option — or filing conflicting elections — can permanently forfeit your right to contest the seizure.
