The US Supreme Court is considering the legality of an executive order issued by former President Donald Trump, which seeks to end birthright citizenship for children born in the United States to parents who are not citizens or lawful permanent residents. This executive order, signed on the first day of Trump's second term in January 2025, argues that such children are not 'subject to the jurisdiction' of the United States. The 14th Amendment of the Constitution grants citizenship to anyone born on US soil, a principle rooted in the English common law concept of 'jus soli'. Trump's attendance at the court marks a historic moment, as he is the first sitting president to do so. A ruling is expected by early summer. In contrast, India has seen changes in its citizenship laws, particularly with the Citizenship Act of 1955, which initially granted birthright citizenship but was amended in 1986 to require that at least one parent be an Indian citizen for children born after that date. This shift reflects a broader trend away from unconditional birthright citizenship in several countries.
