As soon as he took office, President Donald Trump signed an executive order ending birthright citizenship for children born to undocumented or temporarily residing immigrants in the United States, titled “Protecting the Meaning and Value of U.S. Citizenship.”

The decree will officially take effect from February 20, 2025: Any children born after this date will not automatically be granted citizenship if their parents are not U.S. citizens or lawful permanent residents.
At that time, these children born after February 19 will not be able to receive a Social Security number, a U.S. passport, or other important identification documents, creating an uncertain legal status for these children.
Currently, the decree is being challenged in the Supreme Court, as many believe it conflicts with the Constitution:
The 14th Amendment of the U.S. Constitution clearly states that “all persons born in the United States” are U.S. citizens. This has long been understood to apply to anyone born on U.S. soil, regardless of their parents’ legal status. An executive order does not have the authority to override or alter the constitutional provisions.

However, before the court issues an official ruling to block the order, in theory, President Trump’s executive order could be temporarily enforced.
And when it is enforced, it will undoubtedly cause significant difficulties and challenges for those in the U.S. who are not permanent residents or U.S. citizens.
