The U.S. bishops and a Catholic immigration advocacy group supported a lawsuit challenging President Donald Trump's executive order on birthright citizenship. Trump's executive order, signed in January 2025, aimed to restrict birthright citizenship for children born in the U.S. to parents lacking legal status or holding temporary visas. The legal challenge centers on the interpretation of the 14th Amendment's citizenship clause. The Supreme Court is scheduled to hear oral arguments in the case, Trump v. Barbara, on April 1. Various amicus briefs, including one from the U.S. Conference of Catholic Bishops, were filed in support or opposition to the executive order.

President Donald Trump signed an executive order on his first day back in office in January 2025, aiming to end birthright citizenship for children born in the U.S. to parents without legal status or on temporary visas.1 3
The order challenges the 14th Amendment's interpretation, which grants citizenship to those "born or naturalized in the United States, and subject to the jurisdiction thereof."1
Lawsuits followed immediately, with the Supreme Court limiting nationwide injunctions but not ruling on merits yet.1
The U.S. Conference of Catholic Bishops (USCCB) and Catholic Legal Immigration Network Inc. (CLINIC) filed an amicus brief on February 26, 2026, supporting challengers in Trump v. Barbara.1 3
They argue the order lacks historical, legal, and moral support, rooted in Western tradition and Catholic teachings.1
The brief cites Pope Leo XIV's comments on human dignity and treating immigrants humanely.1
The bishops frame birthright citizenship as aligning with Church principles like subsidiarity, social beings, and protecting children's dignity from birth.1 3
They warn ending it denies equal worth to U.S.-born children and revives 14th Amendment injustices.1 3
The brief emphasizes faith compels protesting laws harming innocent children.3
The America First Policy Institute filed a counter-brief, asserting executive and legislative branches have broad authority over immigration and sovereignty.1
They claim power to end birthright citizenship for children of illegal aliens, tourists, or temporary residents.1
Catholic scholars and leaders pushed back, questioning the bishops' view as political rather than doctrinal.3
Joshua Hochschild called for a brief on "actual Catholic social thought," compatible with varied 14th Amendment interpretations.3
Kevin Roberts of Heritage Foundation argued it's a "one-way street" on dignity, ignoring catechism on nations regulating immigration and migrants' duties.3
Andrew Arthur noted most Catholic countries lack unrestricted birthright citizenship, including the Holy See.3
Birthright citizenship stems from the 1868 14th Amendment and 1898 Supreme Court precedent, with limited exceptions.1 3
Originalist scholars note it applied to children of aliens for 235 years until Trump's order.1
Oral arguments in Trump v. Barbara are set for April 1, 2026; outcomes could narrow, limit via Congress, or uphold the practice.3
Examine Catholic doctrine on natural law and citizenship rights
Catholic teaching presents natural law as the moral law inscribed in human nature by God, accessible through reason, and serving as the foundation for ethical discernment and universal human obligations. It is "nothing other than the light of intellect infused within us by God," enabling knowledge of what must be done or avoided, and participates in God's eternal law. This law is universal, extending to all people via human reason, with its principal precepts expressed in the Decalogue, centering on the desire for God, submission to Him, and recognition of others' equality.
The natural law states the first and essential precepts which govern the moral life. It hinges upon the desire for God and submission to him, who is the source and judge of all that is good, as well as upon the sense that the other is one's equal.
Far from static, natural law is dynamic, evolving in expression through historical reflection on human nature, inspiring a universal ethic. It quickens human cognitive and conative powers but requires virtues for full efficacy in moral life, perfecting natural inclinations toward the good. The Gospel's new law fulfills and assumes natural law, enabling its humanizing requirements through grace, overcoming sin's obstacles.
Natural law underpins all human rights and duties, preceding and uniting them, while grounding positive (human-made) law to ensure justice. It protects human dignity from conception to natural death, forming the basis for equitable norms that avoid arbitrariness.
The Europe of human rights must ensure that the objective elements of natural law remain the basis of positive laws... [providing] the fundamental principles [for] equitable juridical norms.
An authentic grasp of natural law guarantees equality and substantiates "rights of man," as it safeguards inalienable dignity. Political authorities must respect fundamental rights, dispensing justice humanely, especially for families and the disadvantaged; citizenship rights serve the common good and cannot be suspended without legitimate reasons. This extends to world citizenship, entailing duties and rights from shared human origin and destiny, condemning discrimination like racism and affirming care for the vulnerable.
Catholic doctrine affirms full citizenship as rooted in human dignity and equality of rights/duties, rejecting discriminatory treatment. Citizens participate in national life, contributing to the common good via faith and reason. Christians, as native citizens, enjoy and exercise full citizenship rights, not as second-class status, but sharing experiences across faiths.
It is therefore crucial to establish in our societies the concept of full citizenship and to reject the discriminatory use of the term minorities, which engenders feelings of isolation and inferiority.
They should enjoy full citizenship and not be treated as second-class citizens or believers... Christians are particularly concerned for the fundamental rights of the human person.
Catholics bear responsibilities as good citizens, influencing society for truth and good, especially aiding the vulnerable, as part of religious duties. Religious freedom is a natural right tied to dignity, attacking which violates objective rights; no ideology, like atheism, may monopolize public citizenship while relegating believers. Exclusion of non-Catholics from political participation on religious grounds alone is unjust, as regimes of religious freedom secure the common good without such discrimination.
States must respect natural law, limiting positive law thereby; serious violations justify resistance to attest alternative views and pursue change.
Natural law is therefore the basis of the right to resistance.
Church and state, as perfect societies, mutually acknowledge rights, respecting autonomy while demanding recognition. Natural law measures political participation against the common good, but presumptions favor equal treatment, avoiding burdens skewed against non-Catholics. Virtues perfect natural law's precepts, aligning actions with eternal law under divine governance.
Summary: Catholic doctrine roots citizenship rights in natural law's universal principles of dignity, equality, and common good, fulfilled in Christ. Authorities must uphold these, with rights to religious freedom and resistance against violations ensuring justice for all.
