Due process is a fundamental right guaranteed by the U.S. Constitution. It protects people against arbitrary government decisions and ensures fairness in legal matters. Both citizens and non-citizens in the U.S. have the right to due process - a chance to defend their rights and to have a fair hearing.

Now, this principle faces a critical test. On April 7, 2025, the Supreme Court deliberated on whether non-citizens have the right to any form of legal process before being removed to foreign countries. Although the justices differed on the specifics of the process, they unanimously reaffirmed that the fundamental right to due process extends to everyone in America, regardless of their legal status.

This case comes amid policy changes and executive actions by the Trump administration resulting in the rapid expulsion of non-citizens, including asylum seekers, often without traditional legal hearings—raising profound questions about the boundaries of constitutional protections in immigration enforcement.

Do non-citizens have the right to due process?

Yes. Under the U.S. Constitution and laws, due process requires just and fair treatment of everyone, regardless of background or immigration status, if their life, freedom, or property is at risk. This includes having the opportunity to defend their rights in court.

But current policies that speed up deportations and limit access to lawyers have made it harder for non-citizens to get a fair chance. Furthermore, some policies are denying non-citizens any process at all before they are expelled. Due process is fundamental to ensuring credible and fair immigration and asylum systems. 

What is habeas corpus?

A vital part of due process is habeas corpus. This protection, which predates the U.S. Constitution, allows individuals to challenge their detention by the government, ensuring that imprisonment is not arbitrary or unlawful. For immigrants, habeas corpus serves as a crucial safeguard, enabling them to contest their detention to ensure that proper legal procedures are followed. It is a fundamental check on government power and a key element in upholding justice. The Supreme Court has reaffirmed twice over the past several weeks that non-citizens have a fundamental right to challenge their detention and removal through habeas corpus.  

Why is a fair hearing important?

Having a chance to go before a judge is an essential part of due process. Hearings allow individuals and the government to present evidence and for the judge to make a decision based on the facts and the law. Individuals get to explain their situation and appeal mistaken decisions, protecting their rights. Fair hearings can lead to better decisions so that the public has confidence in the integrity of the legal system.

Non-citizens facing deportation have a right to due process, which usually includes a hearing before a judge. But current policies are making it even more difficult for non-citizens to get a fair hearing - rushing decisions, limiting the authority of immigration judges, and trying to remove people from the U.S. through rapid deportations that deny them the opportunity to present their case to a judge. 

A former immigration judge previously described immigration court hearings as “death penalty cases in a traffic court setting” because of the high stakes outcomes in a system that has limited protections. Now, fair hearings are becoming even harder to come by.

Why does legal representation matter?

The right to speak with a lawyer and to have your attorney represent you in court is a key part of due process. However, in immigration cases, unlike in criminal cases, lawyers are not provided by the government.

Immigration law is very complex, and some immigrants don’t speak English fluently. Having a lawyer who understands the complexities of the law and the immigration process—and who can present the client’s situation to the judge—is critical. Studies show that people with lawyers are five times more likely to receive the immigration legal status they are entitled to under the law compared with those without legal representation. 

Why are children especially in need?

Children who arrived in the U.S. without their parents need lawyers to protect their rights and ensure they are not sent back to abuse, trafficking or other danger. Without an attorney, children—including infants and toddlers—have to face the complicated immigration process alone, with little chance to defend their rights or avoid deportation.

The risks of third-country removals and expulsions

The practice of removing and expelling non-citizens to "third countries"—nations that are neither their country of origin nor the United States—presents another threat to due process rights when people are not provided proper notice or an opportunity to express fears of persecution, effectively bypassing crucial legal protections.

A landmark case, D.V.D. v. Noem, now challenges this troubling practice. On April 18, 2025, a federal judge ordered the Department of Homeland Security (DHS) to stop sending non-citizens to third countries without providing them with written notice and an opportunity to challenge these removals.

Third-country removals and expulsions manifest in various forms, each with significant due process implications. For instance, in February 2025, hundreds of families and individuals, including many people who were attempting to seek asylum at the southern US border, were sent by the US government to Costa Rica and Panama without an opportunity to apply for protection. In other cases, the government is seeking to deport people who have been through US immigration procedures and received an official removal order by sending them to a country that is not their home country. Recently, immigrants from several Central Asian countries were deported to Uzbekistan, and the US is reportedly in talks to send others to Rwanda and Libya. In these scenarios, it is equally crucial that, at a minimum, adequate notice and an opportunity to challenge the removals are provided before people are sent to a third country. 

Due process and refoulement risks

Sending people to a country they’re not told they’re being sent to and without an opportunity to explain what danger they might face there fundamentally undermines essential due process safeguards and, in some cases, the right to seek asylum. These removals and expulsions can expose people to immediate harm in that third-country, including being held in immigration detention centers or prisons. It even places some of them at risk of being sent back to the home country they originally fled if such a third-country lacks fair and accessible asylum procedures, known as chain refoulement. 

In a critical development, on May 7, 2025, following reports of a planned third-country removal flight to North Africa, litigators filed an emergency motion to prevent the removal of migrants to Libya without prior notice or a chance to explain their fear of being sent there. The court ruled that proceeding with the flight would violate existing orders, leading to its immediate cancellation—highlighting the vital role of judicial review in protecting due process rights.

The Alien Enemies Act: A threat to due process

On March 15, 2025, President Trump declared that the U.S. was under invasion by a Venezuelan gang, Tren de Aragua, and invoked the centuries-old Alien Enemies Act (AEA). Part of the Alien and Sedition Acts of 1798, the AEA gives the U.S. government authority during wars to arrest and expel non-citizens from enemy countries. It has only been used three times in U.S. history, most infamously during World War II as part of the internment of Japanese Americans, which President Ronald Reagan later described as a “grave wrong” and an action “taken without trial, without jury” that was “based solely on race.”

Under President Trump’s current order, Venezuelans as young as 14 (with the exception of U.S. citizens and green card holders) can be expelled from the country without any hearing if they are merely accused of being members of the Tren de Aragua gang. Several lower courts as well as the Supreme Court have paused the administration from removing people under the AEA, but litigation remains ongoing.

Forcibly transporting Venezuelans to a prison outside the U.S. without immigration hearings or any other legal process is a profound break from the Constitution and the American tradition of due process.

How are other recent policies impacting due process?

If due process protections for non-citizens continue to be weakened, countless vulnerable people will be at risk of unjust treatment, including many of the individuals and families supported by the IRC: 

Protecting due process for non-citizens

The International Rescue Committee (IRC) and other groups work to uphold due process for non-citizens by providing legal services, challenging harmful policies, and educating the public. IRC’s programs across 24 U.S. communities offer:

How can I help?

Ensuring due process is not just a legal obligation—it is a safeguard against discrimination and injustice. Policymakers and advocates must work together to uphold these protections and prevent policies that threaten the basic rights of non-citizens in the U.S.
