After quickly reversing a number of Trump-era policies related to immigration, the Biden administration has struggled to deal with large numbers of migrants arriving at the border and has faced legal challenges and setbacks. The administration's continued use of a public health law to expel migrants prompted particular outcry when used to return thousands of migrants to Haiti, which is struggling with political instability and natural disasters. The administration also lost and has appealed cases related to the establishment of the Deferred Action for Childhood Arrivals (DACA) program and to its termination of the Migrant Protection Protocols (MPP). Nonetheless, the administration has succeeded in making some changes, including doubling the 2022 refugee cap, expanding a program to allow certain children from Northern Triangle countries to apply for refugee status, and reopening U.S. borders to most vaccinated travelers. Biden's more fundamental proposal for overhauling the U.S. immigration system remains stalled in Congress.

Upon taking office, the Biden administration immediately reversed a number of Trump administration border and immigration-related policies, including revoking travel bans imposed disproportionately on Muslim-majority countries and halting construction of the border wall.Footnote ¹ Biden also ordered the attorney general and secretary of homeland security to “preserve and fortify” DACA—an Obama-era initiative that “deferred the removal of certain undocumented immigrants who were brought to the United States as children.”Footnote ² In 2020, the Supreme Court blocked the Trump administration's efforts to rescind DACA, but the Trump administration nonetheless refused to accept new applicants.Footnote ³

After these initial actions, the Biden administration then embarked on more fundamental efforts to revise the U.S. approach to immigration and migration. On February 2, Biden issued Executive Order 14,010 on “Creating a Comprehensive Regional Framework to Address the Causes of Migration, to Manage Migration Throughout North and Central America, and to Provide Safe and Orderly Processing of Asylum Seekers at the United States Border.”Footnote ⁴ In the order, Biden pledged to

The order directed the secretary of homeland security to “review and determine whether to terminate or modify” the MPP, a program whereby asylum seekers from third countries arriving at the U.S. border remained in Mexico during the processing of their asylum claims.Footnote ⁶ On June 1, 2021, Secretary of Homeland Security Alejandro N. Mayorkas issued a memo terminating the MPP.Footnote ⁷

Despite these efforts, the Biden administration has faced a number of challenges and setbacks in implementing reforms. Surges of migrants arriving at the U.S. border with Mexico reached an all-time high, with U.S. authorities detaining 1.7 million people during the fiscal year ending in September 2021.Footnote ⁸ Of these individuals, more than 655,000 are from Mexico, and another 700,000 are from El Salvador, Guatemala, and Honduras—collectively known as the “Northern Triangle.”Footnote ⁹ In that time, the Border Patrol expelled over one million migrants, often relying on a public health rule known as Title 42.Footnote ¹⁰

Title 42 of the 1944 Public Health Services Law permits the surgeon general to suspend the entry into the United States of persons from certain countries when he “determines that by reason of the existence of any communicable disease in a foreign country there is a serious danger of the introduction of such disease into the United States” and the suspension is “required in the interest of the public health.”Footnote ¹¹ The Trump administration pioneered the use of Title 42 at the start of the pandemic amidst criticism from immigration rights advocates,Footnote ¹² and the Biden administration reportedly planned to end its reliance on Title 42, before changing course over the summer due to surging arrivals and the COVID Delta variant.Footnote ¹³ DHS has repeatedly emphasized that “Title 42 is not an immigration authority, but a public health authority, and its continued use is dictated by CDC and governed by the CDC's analysis of public health factors.”Footnote ¹⁴ Secretary Mayorkas said in September, “Title 42 is . . . a public health authority to protect the American public, to protect the communities along the border, and to protect the migrants themselves.”Footnote ¹⁵

The use of Title 42 to deport Haitian migrants has sparked particular criticism. Although Haiti has long suffered from political instability and natural disasters,Footnote ¹⁶ conditions have worsened in recent months with the assassination of President Jovenal Moïse in July and a 7.2 magnitude earthquake and flooding in August spurring departures from the country.Footnote ¹⁷ In mid-September, thousands of Haitian migrants arrived at the U.S. border near Del Rio, Texas, overwhelming U.S. authorities’ ability to process them.Footnote ¹⁸ The U.S. Border Patrol detained thousands in “a temporary staging area under the Del Rio International Bridge” for processing, prompting the mayor of Del Rio to describe “squalid conditions” that “resembled a shantytown, with little access to clean water and food and just a few portable toilets.”Footnote ¹⁹ Video released by media outlets showing Customs and Border Patrol agents on horseback swinging reins and charging to confront migrants crossing the river prompted widespread outrage, including from congressional Democrats.Footnote ²⁰ Biden called the actions “horrible,” “outrageous,” and “wrong,”Footnote ²¹ and DHS launched an investigation and suspended the use of horses to patrol the southern border.Footnote ²²

Mayorkas reported that between September 9 and 24, U.S. authorities “encountered” “[n]early 30,000 migrants” near Del Rio.Footnote ²³ Of those, Mayorkas said that through September 24, the United States returned “approximately 2,000 individuals” to Haiti on “expulsion flights” pursuant to Title 42, while thousands returned to Mexico voluntarily, more than 12,000 entered U.S. immigration proceedings, and thousands more awaited processing “to determine whether they will be expelled or placed in immigration removal proceedings.”Footnote ²⁴ White House Press Secretary Jen Psaki explained that “officials had aimed to rapidly turn away single adults and migrant families,” but “pregnant women and families with young children . . . have been allowed to remain in the United States.”Footnote ²⁵ The International Organization on Migration cited a higher figure for expulsions, estimating that the United States deported more than 6,000 people to Haiti between September 19 and October 1.Footnote ²⁶

The use of Title 42 authority to return migrants to Haiti prompted significant pushback within the executive branch. Daniel Foote, the State Department's special envoy for Haiti resigned in protest, stating in a letter to Secretary of State Antony Blinken:

In departing his role as a senior advisor in the State Department's Legal Adviser's Office, Harold Hongju Koh wrote a memo, obtained by Politico, challenging the legality of the administration's continued use of Title 42 authority to expel migrants, particularly to Haiti.Footnote ²⁸ Citing U.S. obligations pursuant to international treaties on torture and refugees, Koh explained:

The administration has received bipartisan criticism for its handling of the Haitian migrants and the border situation more generally. Fifteen Democratic senators along with Senator Bernie Sanders (I-VT) wrote to Blinken and Mayorkas expressing disappointment over the deportations and asking them to find an alternative solution working with governments in the region.Footnote ³⁰ Twenty-six Republican governors, on the other hand, wrote a letter requesting to meet with Biden to discuss “the national security crisis created by eight months of unenforced borders.”Footnote ³¹

In addition to the political backlash, the Biden administration is also facing legal challenges to its use of Title 42. In January 2021, the American Civil Liberties Union filed a class action lawsuit on behalf of families seeking asylum, and on September 16, U.S. District Judge Emmet Sullivan issued an opinion certifying the class and granting a preliminary injunction against enforcement of the policy.Footnote ³² Sullivan held that the plaintiffs are likely to succeed on the merits because he determined at Chevron step one that the statute does not authorize expulsions for public health purposes.Footnote ³³ He stayed the injunction for fourteen days to allow the government time to appeal,Footnote ³⁴ and the D.C. Circuit then stayed the injunction pending appeal.Footnote ³⁵

Human Rights First and other immigration rights groups have also filed a challenge to the Title 42 policy with the Inter-American Commission on Human Rights on behalf of individuals expelled or who could be expelled under the policy.Footnote ³⁶ They filed a request for precautionary measures, arguing that U.S. expulsions refoul asylum seekers and put them at risk of immediate harm.Footnote ³⁷

In addition to litigation over Title 42, the Biden administration has appealed adverse court decisions on both its continuation of DACA and its termination of the MPP.

In 2018, Texas and eight other states filed suit against the United States in the Southern District of Texas, arguing, among other claims, that the establishment of DACA violated both procedural and substantive provisions of the Administrative Procedure Act (APA).Footnote ³⁸ The states alleged that DHS violated the APA by failing to engage in notice and comment rulemaking to establish the program and that DACA violates congressional statutes and thus is “in excess of” statutory authority.Footnote ³⁹ On July 16, 2021, U.S. District Court Judge Andrew S. Hanen granted summary judgment to the states, holding that “DHS violated the APA with the creation of DACA and its continued operation.”Footnote ⁴⁰ The district court agreed with the states that DHS erred in failing to use notice and comment rulemaking to promulgate DACA.Footnote ⁴¹ On the substantive APA claim, the court held at Chevron step one that “DACA is ‘in excess of statutory jurisdiction’ and ‘short of statutory right’” because Congress has specified “laws for removal, lawful presence, and work authorization,” and “[a]gainst the backdrop of Congress's ‘careful plan,’ DHS may not award lawful presence and work authorization to approximately 1.5 million aliens for whom Congress has made no provision.”Footnote ⁴² In issuing a permanent injunction, the court noted current DACA recipients’ significant reliance interests and accordingly emphasized that the injunction neither requires that the government terminate DACA status for those who have already received it nor “take any immigration, deportation, or criminal action against any DACA recipient, applicant, or any other individual that” it “would not otherwise take.”Footnote ⁴³ The injunction prohibits DHS from granting new applications, but stays the injunction with respect to current DACA recipients.Footnote ⁴⁴ The United States and twenty-two DACA recipients who had intervened in the case as defendants have appealed to the Fifth Circuit.Footnote ⁴⁵ In the meantime, in response to the district court decision and in furtherance of Biden's directive to “preserve and fortify” DACA, DHS issued a Notice of Proposed Rulemaking on September 28 to reestablish DACA, engaging in the notice and comment process the district court previously found to be lacking.Footnote ⁴⁶

The Biden administration also appealed a district court decision holding unlawful its attempt to terminate the MPP. Texas and Missouri filed suit to challenge the Biden administration's initial pause and then termination of the MPP, arguing, among other claims, that the termination was arbitrary and capricious for failing to consider factors such as the program's effect in deterring migrants from attempting to reach the United States, the costs to states of terminating the program, and alternatives that would have allowed some continued use of the MPP.Footnote ⁴⁷ U.S. District Court Judge Matthew J. Kacsmaryk agreed with the states and held that the MPP termination was arbitrary and capricious because, among other reasons, DHS “failed to consider several critical factors,” including both “benefits of MPP,” such as “deterring meritless asylum applications,” and consequences of termination, including increased migration to the border and costs to states. Footnote ⁴⁸ The district court also held that because the government declined to return asylum seekers to Mexico and admittedly lacks capacity to detain such persons, the government systematically violated a statutory provision, Section 1225, that “provides the government two options vis-à-vis aliens seeking asylum: (1) mandatory detention; or (2) return to a contiguous territory.”Footnote ⁴⁹ The court rejected the Biden administration's argument that vacatur of the termination memo would cause “chaos” and undermine the government's ability to negotiate and conduct foreign policy related to migration.Footnote ⁵⁰ The court imposed a nationwide injunction against the termination and ordered the government “to enforce and implement MPP in good faith.”Footnote ⁵¹

The Fifth Circuit denied the government's motion to stay the injunction.Footnote ⁵² Largely endorsing the district court's holdings, the court concluded that the government had shown neither a strong likelihood of success on the merits nor that it would suffer irreparable harm absent a stay.Footnote ⁵³ The Supreme Court also denied a stay, stating that the government “failed to show a likelihood of success on the claim that the memorandum rescinding the Migrant Protection Protocols was not arbitrary and capricious.”Footnote ⁵⁴

The Biden administration simultaneously created a new administrative record to terminate the MPP and also worked to restart the program to comply with the district court order. On October 29, DHS issued a memo from Mayorkas again terminating the MPP and released a thirty-nine-page explanation of the termination decision attempting to address the concerns identified by the district court.Footnote ⁵⁵ While explaining that DHS will implement the termination after a judicial decision to vacate the nationwide injunction, DHS announced on December 2 that it had reached agreement with Mexico to restart the MPP, subject to some changes to address humanitarian concerns.Footnote ⁵⁶ On December 13, the Fifth Circuit affirmed the district court's decision on the merits, leaving in place the nationwide injunction requiring the administration to restart the MPP.Footnote ⁵⁷ On December 29, the Biden administration filed a petition for certiorari with the Supreme Court, requesting that the Court hear the case this term.Footnote ⁵⁸

While it continues to litigate some of its signature policy decisions and fundamental revisions to the immigration system remain stalled in Congress,Footnote ⁵⁹ the Biden administration has made a number of other immigration-related policy changes. Reversing a Trump administration policy, DHS announced an end to workplace immigration raids,Footnote ⁶⁰ and the administration has continued its efforts to reunite children separated from their families at the border.Footnote ⁶¹ In addition, the administration has expanded pathways for lawful migration, including doubling the refugee admissions cap from 62,500 in 2021 to 125,000 in 2022,Footnote ⁶² and reopening and expanding eligibility for the Central American Minors program, which allows certain children from El Salvador, Guatemala, and Honduras who have parents and now legal guardians in the United States to apply for refugee status.Footnote ⁶³ In early November, the administration also reversed pandemic-related travel restrictions and reopened U.S. borders to allow entry by those who are fully vaccinated, subject to a negative COVID test within three days of entry.Footnote ⁶⁴ Soon thereafter, however, the emergence of the Omicron COVID variant prompted the administration to tighten testing requirements for all incoming travelers and to restrict travel from countries in southern Africa.Footnote ⁶⁵ The administration revoked the travel restrictions several weeks later as the Omicron variant spread worldwide, including in the United States.Footnote ⁶⁶
