The constitutional mandate to faithfully execute the laws collides with political reality over immigration enforcement. While the law broadly authorizes the removal of individuals present without legal status, public opinion and practical limitations render a policy of mass deportation unworkable. A recent poll indicates only 32% of American adults support making every undocumented immigrant subject to deportation, highlighting the political divide.
A System Overwhelmed
The core obstacle is a crippled adjudication system. Through February, immigration courts faced a backlog of 3.3 million pending cases. Despite reduced border inflows, the system is losing ground. In the current fiscal year, courts have received 202,000 new cases while completing only 334,000. At this pace, the backlog will shrink by fewer than 317,000 cases by September, leaving over 3 million cases unresolved. This gridlock makes the promise of "prompt" removal or asylum hearings impossible for most.
Questionable Judicial Appointments
Compounding the crisis, the Executive Office for Immigration Review has deputized 600 military attorneys as temporary immigration judges for six-month rotations, requiring no prior immigration law experience. Given that immigration law is considered second in complexity only to the tax code, this move is controversial. These appointees receive just two weeks of training before presiding over cases, likely slowing proceedings and increasing appeal rates. Legal challenges may later question the validity of their rulings, potentially forcing re-adjudication.
Enforcement is further hampered by sanctuary jurisdictions. Relying on Tenth Amendment principles, numerous states and localities limit cooperation with federal immigration authorities. The most consequential policy is the refusal to honor ICE detainer requests, which ask law enforcement to hold individuals for 48 extra hours for transfer. In 2025 alone, sanctuary jurisdictions denied 17,864 such requests. This forces ICE to pursue individuals, including those with criminal histories, in the community rather than in secure facilities, raising safety risks for officers and the public.
The consequences are stark. Illinois's sanctuary policies in 2025 led to the release of 1,768 individuals subject to detainers; authorities allege they subsequently committed hundreds of crimes, including homicides and assaults. In a high-profile New York City case, a man released despite an ICE detainer allegedly set a fatal fire, killing adults and a three-year-old child.
A Path Through Incentives, Not Just Force
Given these constraints, eliminating the undocumented population through enforcement alone is not viable. The Department of Homeland Security has therefore supplemented interior enforcement with a voluntary departure program offering a $2,600 stipend and a free flight home. This initiative has resulted in approximately 2.2 million self-deportations in its first year, a significant reduction mechanism. This coincides with a period of unprecedented border control, challenging long-held assumptions about migration flows.
The political friction extends beyond enforcement. Religious leaders have entered the fray, with Pope Leo XIV publicly challenging the administration's approach. Furthermore, polling shows a majority of Americans view current enforcement tactics as overly aggressive, suggesting a disconnect between policy and public sentiment. The scale of the undocumented population remains officially unknown, with estimates varying widely, but the systemic strains it creates are undeniable.
The path forward likely requires a hybrid strategy: rigorous enforcement against threats to public safety, continued pressure on uncooperative jurisdictions, and pragmatic incentives for voluntary departure to shrink the population to a more manageable level. Without addressing the judicial backlog and deep political divisions, any enforcement-only approach will falter under its own weight.
