How would the Texas-Mexico border be managed after independence?

By Texas, for the first time. Today the southern border is run from Washington, and Texas, the state that actually shares it, is a back-seat passenger. As an independent nation, Texas would set its own border and immigration policy and manage its own ports of entry, working with Mexico on the practical mechanics the way neighboring countries do everywhere.

Control of the border becomes a Texas decision

This is one of the core promises of independence. Right now, decisions about who and what crosses the Texas-Mexico border are made by a federal government a long way off, for the whole union, and Texans have watched the results with frustration for years. As a sovereign nation, Texas would make those decisions itself: its own border policy, its own immigration rules within the bounds the movement has already stated, and direct management of its own crossings. The authority over the border would sit with the people who live alongside it, which is the whole point of self-government.

Texas already does much of the on-the-ground work

Texas is not starting from zero at the border. The state already commits its own money and personnel to border security, operating state law enforcement along the Rio Grande today. The institutions, the Department of Public Safety, state troopers, the capacity to coordinate large operations, already exist and already work the border. Independence does not require Texas to conjure a border apparatus overnight. It hands Texas full authority over, and full funding for, work the state is already partly doing.

The river is a shared resource, governed by a treaty that survives the change

The Rio Grande is both the boundary and a shared water supply, and that is managed by long-standing agreement, not by ownership. The 1944 treaty on the waters of the Colorado and Tijuana Rivers and the Rio Grande, administered by the binational International Boundary and Water Commission, sets Mexico's delivery obligation to the US side, on the order of 350,000 acre-feet a year averaged over five-year cycles, with Texas the principal beneficiary. Boundary and water treaties are exactly the kind that carry over when sovereignty changes, so the framework continues, with Texas stepping in as a party in its own right. For the first time, the state most affected by Rio Grande water would represent its own interests directly, instead of relying on federal negotiators in distant Washington. We cover the treaty-succession law in the water and international answers.

Cooperation with Mexico is the normal, expected way neighbors run a border

A border has two sides, and managing it is something neighboring nations do together on the practical mechanics: ports of entry, crossing procedures, trade lanes, and shared infrastructure. We do not assume any particular commitment from the Mexican government here; that is theirs to make. What changes for Texas is authority and direct dealing. Instead of the United States speaking for Texas in talks with Mexico about the border Texas shares, Texas would deal with Mexico government to government, neighbor to neighbor, on the issues Texans live with every day. The enormous trade that already crosses that border, more than 300 billion dollars a year in two-way commerce by TNM's analysis of state trade data, gives both sides a powerful interest in keeping crossings orderly and open to lawful traffic.

Immigration policy at the border, stated honestly

On the immigration question specifically, we hold to the movement's existing position and go no further: Texas wants a secure border and a sensible, legal, structured immigration policy sized to what Texas can absorb and to the workers its economy needs, with citizens given employment priority. That is the live answer, and this one takes no position beyond it. What independence changes is not the addition of some new, invented policy. It is who holds the authority to set and enforce the policy: Texas.

The bottom line

After independence, the Texas-Mexico border would be managed by Texas, funded by Texas, and run in direct cooperation with Mexico, with the Rio Grande water framework carrying over and Texas finally speaking for itself. The authority over the southern border would belong to the Texans who actually live on it.
