The debate over birthright citizenship in the United States has surfaced once again, raising questions about its constitutional footing and the nation’s historical trajectory in contrast to global practices. Central to this discourse is President Donald Trump’s executive order aimed at restricting birthright citizenship, which has led to a new wave of scrutiny and legal challenges. The order seeks to deny U.S. citizenship to certain children born on U.S. soil based on their parents’ citizenship or immigration status. Legal professionals and courts have largely regarded the executive order as potentially unlawful, and the issue is anticipated to reach the Supreme Court, where justices will examine its alignment with the prevailing interpretation of the Fourteenth Amendment.
The Fourteenth Amendment of the U.S. Constitution, enacted in 1868, enshrines the principle of jus soli, or “right of the soil.” This approach grants citizenship to anyone born in the U.S. The concept contrasts with jus sanguinis, or “right of blood,” which is prevalent in many other developed nations, wherein citizenship is based on the nationality of one’s parents. Germany, Japan, and Nordic countries, for example, primarily adhere to jus sanguinis, which leverages biological lineage as the basis for citizenship. For a deep dive into the history and implications of jus soli and jus sanguinis, see the Immigration Matters series by César Cuauhtémoc García Hernández.
Historically, jus soli has been common in the Americas, with countries such as Canada and Brazil adopting similar approaches to the United States in recognizing the birthplace as a determinant of citizenship. This tradition stems from colonial histories where European powers displaced indigenous populations, setting the stage for a nationality based on land rather than lineage. In contrast, jus sanguinis is more typical of countries with less extensive colonial pasts.
The distinction between these systems was not just born out of philosophical considerations but historical pragmatism. The United Kingdom, for example, employed jus soli when it was expanding its empire, thus ensuring that its own nationals retained citizenship regardless of where in the realm they resided. However, the U.K. revised its stance in 1983 by introducing the British Nationality Act, which now mixes jus soli with jus sanguinis.
While proponents of Trump’s executive order claim the U.S. should align with most other developed countries in adopting a more restrictive citizenship policy, they do not specify which nations serve as their benchmark for development. The potential impact of aligning U.S. citizenship laws with global norms could be significant, influencing not just immigration statistics, but the cultural and legal fabric of the nation.
