In January, former President Donald Trump will reclaim the White House after years of vowing to unleash an unprecedented overhaul of the immigration system in the United States. With mass deportation as a central promise of his campaign, Trump will undoubtedly build on the sweeping crackdown that marked his first term.
He has already pledged to bring back harmful policies. Trump has promised to restore the travel prohibition on foreigners from Muslim-majority countries (often called the “Muslim ban”). He wants to revive “Remain in Mexico”—which left thousands of vulnerable migrants and asylum seekers awaiting court hearings stranded in dangerous border towns. Trump has also taken his anti-immigrant rhetoric and proposals to new heights, notably by pledging to carry out the “largest domestic deportation operation in American history” and attacking legal immigration.
Indiscriminate workplace raids, massive detention camps, and around-the-clock deportation flights. That’s the radical vision to remove millions of undocumented immigrants put forward by Trump.
Trump’s efforts to reshape the immigration landscape are likely to start immediately. Appearing on Fox News the morning after the election, the president-elect’s spokesperson Karoline Leavitt celebrated a “resounding victory” and a “mandate to govern as he campaigned to deliver on the promises that he made, which include, on day one, launching the largest mass deportation operation of illegal immigrants.”
Immigrant rights groups and lawyers have been diligently preparing for the possibility of a Trump comeback. Not unlike the first time around, they will inevitably pursue strategic litigation to stop some of the next administration’s harshest, and possibly unlawful, policies. “I’ve sued every president since George W. Bush, including Presidents Obama and Biden,” Karen Tumlin, founder and director of Justice Action Center, said in a statement. “We have a simple message for President-elect Trump or his deputies if they decide to make good on their despicable plans: We will see you in court.”
Still, the breadth and depth of Trump’s agenda will have lasting impact, not only on immigrants who will directly bear the brunt of a heightened militarized immigration enforcement environment, but also on all Americans.
Here’s how:
Launch Mass Deportation
Indiscriminate workplace raids, massive detention camps, and around-the-clock deportation flights. That’s the radical vision to remove millions of undocumented immigrants put forward by Trump and his senior adviser on immigration Stephen Miller. They would attempt to accomplish it by invoking a 18th-century wartime law known as the Alien Enemies Act—last used during World War II for the internment of Japanese, Italian, and German nationals—and deploying the full force of law enforcement agencies and the US military in violation of due process rights and the law.
A mass deportation campaign would permanently change the United States. It could lead to racial profiling, the potential separation of families, and the wrongful deportation of Americans and lawful residents. It would also ruin the economy.
The logistical and practical challenges of purging even one million people a year are considerable, not to mention the moral and human devastation. But, if realized, a recent analysis by the American Immigration Council found that such a project would cost $967.9 billion over more than a decade. The deportation of immigrant workers who are the backbone of so many critical industries would also break the economy, resulting in an estimated GDP drop of up to 6.8 percent.
End Birthright Citizenship
Trump promised to sign an executive order on day one to end the long-standing constitutional guarantee of citizenship for children born in the United States regardless of their parents’ immigration status. The order would instruct federal agencies to require that at least one parent be a US citizen or lawful permanent resident for the children to be granted automatic citizenship.
“This current policy is based on a historical myth and a willful misinterpretation of the law by the open borders advocate,” Trump has said. Birthright citizenship is enshrined in the 14th Amendment of the Constitution—and reaffirmed in Supreme Court decisions—which states that, with very few exceptions, “all persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the state wherein they reside.”
Revive the “Muslin Ban”
During his first term, Trump took 472 executive actions in his bid to reshape the immigration system. One of them was the infamous “Protecting the Nation From Foreign Terrorist Entry Into the United States” order, which permanently suspended the resettlement of refugees from Syria and barred the entry of travelers from seven Muslin-majority countries—Iraq, Iran, Libya, Somalia, Sudan, Syria, and Yemen. The policy created instant chaos, sparked international repudiation, and galvanized Americans all over the country.
Trump has vowed to restore the so-called “Muslim ban.” The original iterations faced repeated legal challenges. Federal appeals courts ruled against the Trump administration concluding that the executive order “stated national security interest was provided in bad faith” and “drips with religious intolerance, animus, and discrimination.” But in a 5-4 decision from June 2018, the Supreme Court allowed the Trump administration to carry out a version of the ban. On his first day in office, President Joe Biden issue a proclamation reversing it.
End TPS and DACA
Hundreds of thousands of people from all over the world who currently benefit from Temporary Protected Status (TPS)—granted to those fleeing wars, natural disasters, and other country-specific circumstances—are at risk of losing protection against deportation.
That includes nationals of Haiti, Yemen, Afghanistan, Ukraine, and Venezuela. The Heritage Foundation’s Project 2025 Playbook crafted by a number of administration-in-waiting former officials specifically calls for the repeal of TPS designations.
While in office, Trump tried to rescind the Obama-era Deferred Action for Childhood Arrivals (DACA) program that shields from deportation the undocumented youth brought to the United States as children. There were as many as 535,030 active DACA recipients, as of June 2024. Miller has said a second Trump administration would again attack the program, whose fate already lies with the courts. “It would be absolutely catastrophic,” Michelle Ming, political director at United We Dream, says of the prospect of tens of thousands of young people losing status. “It would destroy families. It would destroy entire communities.”
Roll Back Refugee Resettlement
In a September social media post where he introduced to concept of remigration, Trump said he would “suspend refugee resettlement.” The first Trump administration dealt a massive blow to the US refugee resettlement program and it likely wouldn’t be different this time. In September, Trump said he would “ban refugee resettlement from terror infested areas like the Gaza Strip.”
As president, he set an annual cap of 15,000 refugee admissions. The number of admissions went from 84,994 during Barack Obama’s last year in office to a record low of 11,814 in 2020. Ultimately, the Trump administration resettled fewer refugees than any other going back at least to the Jimmy Carter presidency. Upon taking the White House, President Joe Biden worked to restore the program, resettling 100,034 refugees in fiscal year 2024—the most in decades.
Restrict Legal Immigration
While Trump has tried to signal that he’s in favor of legal immigration pathways, his allies have been preparing the terrain to severely restrict them. “Decades of ‘we’re not against legal immigration’ will culminate in the largest cut to legal immigration in US history,” David J. Bier, director of immigration studies at the Cato Institute, posted on X.
Their plans include severely curbing asylum, ending diversity lottery visas, and doing away with temporary legal programs like parole that have allowed immigrants from countries such as Haiti, Venezuela, Nicaragua, and Cuba to come to the United States after being vetted and securing a sponsor. They could even resuscitate the public charge rule making it harder for low-income immigrants to qualify for visas and green cards.
Immigration lawyers have additionally warned that, in a second Trump administration, visa processing might be subject to delays and increased denial rates. “If Donald Trump is elected president in November 2024,” the National Foundation for American Policy stated, “he should be expected to restrict legal immigration, including green cards and [high-skilled] H-1B visas.”
The Project 2025 agenda contemplates undermining T and U visas for undocumented immigrant victims of trafficking and certain crimes who cooperate with law enforcement. (These temporary protections serve as a powerful tool to encourage victims to report crimes and keep their communities safe.) It also envisions winding down crucial temporary agricultural worker programs.
Projecting a scenario where Trump’s policies result in less immigration and even more people leaving the United States than entering, a Brookings Institution analysis concluded the GDP in 2025 would be $130 billion lower than under a Harris administration.
