This claim is exaggerated to the point that the claim is not true:

The claim that “no other country in the world allows this” (referring to unconditional birthright citizenship for children of undocumented immigrants) is false.

While the United States is one of the few nations with unconditional jus soli (citizenship by birth alone), it is not the only one. According to a 2026 analysis by the Pew Research Center and the Global Citizenship Observatory, there are 32 other countries that grant automatic citizenship to anyone born on their territory, regardless of their parents’ legal status or nationality https://www.pewresearch.org/short-reads/2026/03/31/us-style-birthright-citizenship-is-uncommon-around-the-world/ https://www.usatoday.com/story/news/politics/2026/04/01/countries-birthright-citizenship-laws-2026/89420206007/.

1. Countries with Unconditional Birthright Citizenship

Like the U.S., 32 nations grant citizenship automatically to almost anyone born within their borders, including children of undocumented immigrants, tourists, or temporary workers (with the standard exception of children of foreign diplomats) https://www.pewresearch.org/short-reads/2026/03/31/us-style-birthright-citizenship-is-uncommon-around-the-world/ https://worldpopulationreview.com/country-rankings/countries-with-birthright-citizenship:

• The Americas: Canada, Mexico, Brazil, Argentina, Colombia, Peru, Chile (with specific cavears below), and most Caribbean and Central American nations (e.g., Jamaica, Cuba, El Salvador, Guatemala).
• Other Regions: Pakistan, Tuvalu, Mozambique, and Chad https://www.pewresearch.org/short-reads/2026/03/31/us-style-birthright-citizenship-is-uncommon-around-the-world/.

Note on Chile: While Chile is often listed as having unconditional jus soli, its laws have evolved. A 2021 legal reform narrowed the definition of “transient foreigner” to prevent abuse, but it maintains a strong citizenship-by-birth principle with specific anti-statelessness safeguards https://unioncitizenship.com/countries-with-birthright-citizenship/

2. Countries with Restricted (Conditional) Birthright Citizenship

Some countries grant citizenship by birth, but with conditions that the U.S. does not have. In these nations, at least one parent must usually be a legal resident, a citizen, or also born in the country https://www.csmonitor.com/USA/Justice/2026/0401/birthright-citizenship-supreme-court-trump:

• Legal Residence Required: Australia, Germany, Ireland, the United Kingdom, and New Zealand only grant automatic citizenship if a parent is a permanent resident or citizen.
• Double Jus Soli (Parent also born there): France, Belgium, and Spain may grant citizenship to a child born there if one of the parents was also born in that country
