McAllen-Rio Grande Valley Becomes the U.S.-Mexico Border Sector With the Most Migrant Arrests in July 2026
The McAllen sector (Rio Grande Valley) became the area with the highest number of migrant arrests along the southern U.S. border during July 2026. The phenomenon is attributed to a notable increase in the flow of Mexican citizens fleeing their communities due to insecurity.
Rising Numbers in the Rio Grande Valley
- Arrests in July: The Border Patrol apprehended 2,438 migrants in this sector.
- Exponential growth: The figure represents a 157 percent increase compared with the 949 arrests recorded in July 2025.
- Border leadership: McAllen surpassed the El Paso, Texas, region, which recorded 1,528 apprehensions. It was the only sector along the entire border to exceed 2,000 arrests during the month.
The phenomenon of increased surveillance and arrests extends to other areas of Texas. The Laredo sector reported 1,322 arrests in July, representing a 155 percent increase compared with the previous year.
Background on Security Figures
The increase coincides with a tightening of detention policies in the United States implemented so far this year. According to reports from U.S. Immigration and Customs Enforcement (ICE), July 2026 marked an intensification of border operations that resulted in at least 49,571 total federal arrests, the highest monthly figure reported in recent periods.
Meanwhile, although official indicators in Mexico point to a gradual decrease in the general perception of urban insecurity—standing at 59.8 percent midway through the year—civil society organizations and local reports such as the Gallery of Horror reveal that specific areas continue to experience high levels of extreme violence, massacres, and high-impact events. This regional disparity is forcing entire populations to move northward.
Change in the Migrant Profile: The Return of Mexicans
Unlike recent years, when the massive arrival of people from Venezuela, Cuba, Haiti, and Nicaragua predominated, Mexican citizens are once again the largest group of undocumented migrants apprehended by U.S. authorities.
Violence, the Main Trigger
Priest Francisco Gallardo López, head of the Human Mobility Ministry of the Diocese of Matamoros-Reynosa, explained that this increase is directly linked to Mexican families and groups fleeing insecurity in their communities of origin.
Despite the increase in migrant arrests, the priest clarified that shelters in the border region have not yet reached the critical overcrowding levels experienced in previous years during waves of migrants from Central America, South America, and the Caribbean.
