Mexico’s Birthright Citizenship Gives Migrant Children Nationality as U.S. Case Looms

Granting citizenship at birth can change migrants' lives by giving children nationality that lets parents apply for residency as the U.S. Supreme Court prepares to rule.

Overview

  • Mexico automatically grants citizenship to children born on its soil, and a Haitian family in Tijuana says their granddaughter’s Mexican birth has improved her mobility and future prospects.
  • Mexican law allows parents of citizen children to apply for permanent residency, a pathway that has helped many Haitian families regularize their status in Tijuana.
  • About three dozen countries, mostly in the Americas, use birthright citizenship; the Dominican Republic’s 2007 rollback and the later emergence of up to 130,000 stateless people show the risks of curtailing jus soli.
  • The U.S. Supreme Court is expected to review President Trump’s Jan. 20, 2025 order that seeks to deny birthright citizenship to some children of noncitizen parents, a ruling that could alter legal rights and migration incentives.
  • Wednesday’s coverage emphasizes the human effects of jus soli, notes Mexico does not publish figures on births to noncitizen parents, and recalls IOM data showing a 2021 surge in Haitian migrants with at least 10% of arriving women pregnant.
