Increased Enforcement at the Northern U.S. Border Yields Higher Illegal Alien Encounters

The northern border of the United States stretches over 5,500 miles, including the boundary with Canada's Alaska, making it the longest land border globally. Historically, this area has presented challenges for patrol and enforcement; however, Customs and Border Protection (CBP) has recently redeployed agents from processing centers back to active field patrols, which has enabled them to catch illegal aliens that previously eluded authorities. According to Hilton Beckham, an assistant commissioner with CBP, this increased focus includes operations targeting individuals already inside the country.

As enforcement ramps up, many sectors along the southern border have reported a decrease in illegal encounters, yet certain northern sectors, particularly the Detroit Sector, are experiencing a rise. In fiscal year 2024, there were 624 encounters reported in the Detroit Sector, which encompasses states like Illinois, Indiana, Michigan, and Ohio. That number has doubled to 1,281 encounters in fiscal year 2025, indicating a significant surge in activity following intensified enforcement measures attributed to a change in administration.

President Donald Trump, upon returning to the presidency, prioritized border and immigration policy, repealing many policies established during the Biden administration. Measures such as the “Remain in Mexico” policy and increased border security initiatives point to a decisive shift in border enforcement strategies. Although the Detroit Sector traditionally has lower illegal crossing rates compared to the southern border, local law enforcement is now collaborating more closely with CBP to identify immigration violations.

Many of those apprehended have initially crossed through the southern border, indicating a trend of migration patterns shifting towards the northern regions. Individuals who evade capture upon entering the U.S. are termed "gotaways." The Biden administration previously marked around 2 million known gotaways who entered undetected, with undisclosed numbers likely having crossed without being caught on surveillance.

Experts like Lora Ries from The Heritage Foundation note that the northern border's lesser infrastructure and lower agent presence historically made it easier for illegal crossings, leading to high gotaway rates. According to Ries, the enhanced CBP efforts to catch illegal immigrants at the northern border are a positive development, reflecting the success of recent legislative efforts aimed at bolstering border security.

In alignment with these changes, Trump recently signed a considerable funding bill aimed at the Department of Homeland Security. This "Big, Beautiful Bill" allocated substantial resources for completing border wall construction and investing in new surveillance technologies. CBP continues to encourage local communities to remain vigilant and report any suspicious immigration activities.
