He mentioned that despite previous attempts, the emergence of the COVID-19 epidemic forced him to give priority to other issues.

Trump thinks this practice is "absurd" and plans to end it. The "birth citizenship" in the United States is based on the 14th Amendment to the Constitution in 1868, which stipulates that anyone born in the United States and subject to its jurisdiction is an American citizen.

This principle was supported by the Supreme Court in the case of Golden Virtue in 1898. Trump has always opposed this legislation, and plans to prevent the so-called "maternity travel to the United States" through administrative orders or institutional rulemaking procedures, that is, pregnant women go to the United States to give birth to their children in order to automatically obtain US citizenship.

On January 20th, local time, U.S. President Trump signed an executive order at the White House that children born in the United States to illegal immigrants or those holding temporary visas will no longer automatically obtain U.S. citizenship. The executive order will take effect 30 days after issuance and will apply to relevant persons born in the United States at that time.

The content of the executive order states, “As defined in the executive order, the following two categories of persons will no longer automatically enjoy the privileges of U.S. citizenship: individuals whose mothers are illegally residing in the United States and whose fathers were not U.S. citizens or lawful permanent residents at the time of their birth; An individual whose presence is legal but temporary (such as through the Visa Waiver Program or entering on a student, work, or tourist visa) and whose father was not a U.S. citizen or lawful permanent resident at the time of his or her birth.”
