Irregular migration at the U.S.-Mexico border has emerged as a defining political issue in the 21st century. One challenge has been the U.S. government’s ongoing struggle to manage surges in border arrivals. Streamlining asylum processing — deporting those who do not qualify and resettling those who do — could help reduce political tensions. Migration patterns also fluctuate for reasons beyond U.S. control. Encounters at the U.S.-Mexico border reached record highs in 2023 before dropping sharply in 2024, a trend seen repeatedly over the past 15 years.

An increasing number of Americans view immigration as a long-term issue that requires stronger measures. Diverging views on immigration have contributed to deep divisions within the American electorate, with candidates advocating for stricter policies gaining support. President Donald Trump, for example, has linked irregular migration with risks to national security, public safety, and the economy. In both of his presidential campaigns, he pledged swift action on immigration, with mass deportation of undocumented migrants being a cornerstone of his second term program.

This brief explores the impacts of Trump’s immigration policy, with particular attention to the economic and social costs of large-scale deportations.
