Document Introduction

Following President Trump's inauguration on January 20, 2025, his administration launched a series of executive actions and initiatives centered on the enforcement of federal immigration laws. These actions span key areas including border control, processing of entry applications, refugee admissions, and interior enforcement, with some policies reinstating measures from his first term. This report, serving as a professional legal analysis provided by the Congressional Research Service for legislative debate, systematically outlines the content framework and legal basis of these core actions.

The report focuses on the Trump administration's signature immigration policies. These include the proclamation on entry restrictions related to border invasion issued under constitutional guarantee clauses, which calls for suspending the entry of certain foreign nationals and restricting their right to apply for asylum; the reinstatement of new rules for processing entry applications such as the Migrant Protection Protocols (MPP), the termination of the CBP One appointment function and categorical parole programs from the Biden administration era; and measures to enhance southern border security and physical barrier construction by declaring a national emergency to mobilize military resources.

Regarding interior immigration enforcement and national security, the report details the government's specific measures to strengthen immigration law enforcement. These include expanding the scope of expedited removal, authorizing local officials to participate in immigration enforcement, restricting federal funding for sanctuary jurisdictions, and designating specific transnational criminal organizations as national security threats, utilizing Guantanamo facilities to detain related foreign nationals. Furthermore, concerning birthright citizenship stipulated by the Fourteenth Amendment, the executive order issued by the Trump administration imposes restrictive definitions on its scope of application, sparking significant constitutional controversy.

The report also emphasizes the legal challenges facing these policies. Some policies have been subject to lawsuits alleging violations of the separation of powers, the Administrative Procedure Act, and constitutional guarantees, involving key legal issues such as the applicable boundaries of guarantee clauses, the legality of presidential entry restriction powers, and due process protections in expedited removal procedures. Several federal courts have issued preliminary injunctions against the executive order related to citizenship, while judicial review of policies on border security and interior enforcement remains ongoing.

Based on federal legal statutes, executive order texts, and judicial cases, this report provides an authoritative legal perspective for understanding the significant adjustments in U.S. immigration policy in early 2025. Its analytical conclusions hold important reference value for legislators, policymakers, and legal practitioners.
