The US Constitution, which became effective on March 4, 1789, empowers Congress to pass federal immigration laws and citizenship laws. The Constitution guarantees certain rights to immigrants, including the right to due process and equal protection under the law. The Fifth Amendment, Fourteenth Amendment, and Sixth Amendment are particularly relevant to the discussion of immigrants' rights. The Fourteenth Amendment, ratified in 1868, significantly expanded citizenship rights, asserting that all individuals born or naturalized in the US are citizens, regardless of their parents' status. This amendment also provides key rights for immigrants, such as birthright citizenship, equal protection, and due process. The Supreme Court has generally assigned the power to regulate immigration to Congress, but it has also ruled that immigrants are entitled to certain constitutional protections.

What You'll Learn

The Fifth Amendment and due process
Due process is a fundamental principle in the US legal system, guaranteeing that all individuals receive fair and just treatment under the law. In the context of immigration, due process rights include the right to a fair hearing, the right to present evidence, and the right to not be detained indefinitely. The Supreme Court has affirmed that aliens who have physically entered the United States are generally entitled to due process protections, as established in cases such as United States ex rel. Vajtauer v. Comm’r of Immigration in 1927.
The Fifth Amendment's due process clause ensures that immigrants facing deportation or removal have certain procedural rights. For example, in Reno v. Flores (1993), the Supreme Court ruled that the Fifth Amendment entitles aliens to due process in deportation proceedings, including the right to have children released to their parents or a licensed program within 20 days. Additionally, in Zadvydas v. Davis (2001), the Court interpreted a statute authorizing the detention of aliens awaiting removal as having implicit time limits, concluding that indefinite detention would raise serious constitutional concerns.
However, the application of due process rights in immigration cases can be complex. Immigration courts may have lower standards for evidence, and hearsay may be admissible, making it challenging for immigrants to defend themselves. Furthermore, while the Sixth Amendment guarantees the right to legal counsel in criminal cases, deportation proceedings are often considered civil cases, and immigrants may not always have access to legal representation.
In conclusion, the Fifth Amendment's due process clause plays a crucial role in protecting the rights of immigrants in the United States. While the exact scope of these protections is still debated, it is clear that all "persons" within US jurisdiction, regardless of citizenship or legal status, are entitled to certain fundamental rights and fair treatment under the law.

Fourteenth Amendment and citizenship
The Fourteenth Amendment (Amendment XIV) to the United States Constitution, passed by Congress on June 13, 1866, and ratified on July 9, 1868, is one of the most consequential amendments, addressing citizenship rights and equal protection under the law at all levels of government. The Citizenship Clause, which forms the first sentence of the Fourteenth Amendment, states: "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." This clause reversed a portion of the Dred Scott v. Sandford decision, which had declared that African Americans were not and could not become citizens of the United States.
The Fourteenth Amendment was a response to issues affecting freed slaves following the American Civil War, and its enactment was bitterly contested. The amendment sought to entrench the principle of citizenship for all persons born or naturalized in the United States into the Constitution to prevent it from being struck down by the Supreme Court or repealed by a future Congress. The framers of the Fourteenth Amendment also intended to nationalize the Bill of Rights by making it binding upon the states.
The Citizenship Clause has been interpreted by the Supreme Court to mean that children born in the United States receive birthright citizenship, regardless of whether their parents are non-citizen immigrants. This interpretation has been challenged by some, including US President Donald Trump, who issued Executive Order 14160 on January 20, 2025, titled "Protecting the Meaning and Value of American Citizenship," intending to end birthright citizenship in cases where neither parent is a citizen or lawful permanent resident of the US. This executive order was met with legal challenges, with a US district judge issuing a temporary restraining order and referring to it as "blatantly unconstitutional."
The Fourteenth Amendment also guarantees that no state shall make or enforce any law that abridges the privileges or immunities of US citizens, nor shall any state deprive any person of life, liberty, or property without due process of law. This amendment has been invoked in numerous Supreme Court cases, including Shelley v. Kraemer (1948), where the Court held that the amendment's historical context of countering discriminatory Black Codes in the southern states must be considered in its interpretation.

Fourteenth Amendment and equal protection
The Fourteenth Amendment (Amendment XIV) to the United States Constitution was adopted on July 9, 1868, as one of the Reconstruction Amendments. It addresses citizenship rights and equal protection under the law at all levels of government. The Fourteenth Amendment was a response to issues affecting freed slaves following the American Civil War, and it was bitterly contested.
Section 1 of the Fourteenth Amendment states that all persons born or naturalized in the United States and subject to its jurisdiction are citizens of the United States and of the state in which they reside. It prohibits states from making or enforcing any law that abridges the privileges or immunities of US citizens. Additionally, it protects the rights to life, liberty, and property, ensuring that no person can be deprived of these rights without due process. Finally, it guarantees equal protection under the law, stating that no person within its jurisdiction shall be denied the equal protection of the laws.
The Fourteenth Amendment has been interpreted by the Supreme Court to extend birthright citizenship to all persons born in the United States and to prevent the enforcement of discriminatory laws. For example, in Meyer v. Nebraska (1923) and Pierce v. Society of Sisters (1925), the Supreme Court struck down anti-immigrant state education laws as violations of substantive due process. In Plyler v. Doe (1982), the Supreme Court prohibited state governments from restricting public education based on a child's immigration status, citing the Fourteenth Amendment.
The Fourteenth Amendment's Due Process Clause incorporates the Bill of Rights against state governments, while the Fifth Amendment's Due Process Clause has been used for reverse incorporation of the Equal Protection Clause against the federal government. This was demonstrated in Bolling v. Sharpe (1954), where the Supreme Court used this doctrine to prevent the federal government from maintaining segregated public schools in Washington, D.C.
The Fourteenth Amendment has had a significant impact on immigration law and policy in the United States, ensuring that all persons within its jurisdiction, regardless of their legal status, are entitled to equal protection and due process under the law.

Sixth Amendment and legal counsel
The Sixth Amendment states that "In all criminal prosecutions, the accused shall... have the assistance of counsel for his defence". This right to legal counsel has always protected non-citizens just as it does citizens. However, in practice, this does not always occur in immigration cases.
Immigrants in immigration court do not have a right to government-appointed counsel. Only 37% of immigrants secure legal representation in their removal cases, with detained immigrants being the least likely to obtain representation. Only 14% of detained immigrants acquired legal counsel, compared to two-thirds of non-detained immigrants. This is because most deportation proceedings are civil rather than criminal cases, so the right to legal counsel often doesn't apply.
The Trump administration's zero-tolerance policy requires most illegal border crossings to be tried as criminal cases, except when parents cross the border with children. However, crossing the border illegally is a misdemeanour, so the government is not required to provide counsel.
The Supreme Court ruled in the 1963 case Gideon v Wainwright that if a person is too poor to hire an attorney, the government must appoint one. However, this does not apply to immigration cases. Immigrants facing removal are entitled to due process, but the bar for what constitutes evidence is lax in immigration court. Documents do not have to be authenticated, and hearsay is admissible, making it very difficult for immigrants to defend themselves without legal representation.
The lack of legal representation has a profound impact on immigrants' outcomes in removal proceedings. It is much more difficult for immigrants to prove they have a legal claim to remain in the US without legal counsel.

The right to education
The Supreme Court's ruling in Plyler v. Doe has significant implications for the education of undocumented children. It means that these children cannot be prohibited from enrolling in public schools solely based on their immigration status. This ruling is in line with the broader interpretation of the Constitution, which applies to "persons" or "people" rather than just "citizens". As a result, basic rights such as freedom of speech, religion, and due process extend to both citizens and non-citizens who are physically present in the United States.
While the right to education for undocumented children has been established, the specific implementation and availability of educational resources for this population may vary across different states and localities. The quality and accessibility of education for undocumented children can be influenced by factors such as local policies, funding, and community support.
In conclusion, while there is no explicit mention of a "right to education" in the US Constitution, the 14th Amendment and the Supreme Court's interpretation in Plyler v. Doe have established that undocumented migrant children have a right to access free public education. This ruling upholds the principles of equal protection under the law and recognises the importance of education in fostering a productive and cohesive society.

Frequently asked questions
The US Constitution applies to undocumented immigrants, as it uses the terms "people" or "person" rather than "citizen". This means that basic rights such as freedom of religion and speech, the right to due process and equal protection under the law apply to citizens and noncitizens.
The Fourteenth Amendment, ratified in 1868, significantly expanded citizenship rights, asserting that all individuals born or naturalized in the US are citizens, regardless of their parents' status. This principle of jus soli (right of the soil) has allowed many immigrants and their children to achieve citizenship. It also provides key rights for immigrants and their families such as birthright citizenship, equal protections, and due process.
The US Constitution empowers Congress to pass federal immigration and citizenship laws providing such laws do not violate the provisions of the Constitution itself, particularly those included in the Bill of Rights and the Fourteenth Amendment. The Supreme Court has generally assigned the constitutional power to regulate immigration to Congress, with executive authority mainly derived from congressional delegations of authority.
