The U.S. Trump administration is considering measures to restrict the entry of pregnant women from around the world into the United States.

This is a countermeasure following court rulings that declared President Trump's executive order—which sought to limit birthright citizenship, the practice of granting citizenship to babies born in the U.S.—unconstitutional.

According to the U.S. political news outlet Axios, following the U.S. Supreme Court ruling, President Trump’s aides and his core supporters, known as the MAGA base, have quickly pivoted to this new plan.

Stephen Miller, the White House Deputy Chief of Staff who designed the Trump administration's hardline immigration policies, argued to the outlet, "We need to look very carefully at who is coming into the United States, even if it is temporary, because people are coming to have babies on U.S. soil and those babies will have citizenship for life."

Following the Supreme Court's ruling to maintain birthright citizenship, President Trump ordered Congress to pass legislation to supplement or replace it.

In addition, he has directed federal prosecutors to prioritize the investigation and prosecution of "birth tourism" cases.

However, the proposal to ban the entry of pregnant foreigners to stop birth tourism is facing criticism.

The National Women's Law Center in the U.S. pointed out, "The idea that data about who is pregnant and what their pregnancy status is could be handed over to the federal government, and even further to state governments, is a truly dangerous proposal."

Some also argue that the number of babies born through birth tourism is relatively small, as there are approximately 3.6 million births in the U.S. each year, while the number of babies born to foreigners visiting the U.S. is estimated at 20,000 to 26,000 annually.

Furthermore, it has been pointed out that several athletes, such as Folarin Balogun, a key striker for the U.S. national soccer team that advanced to the Round of 32 in the North and Central American World Cup, would not have been eligible to play for the U.S. team at all without birthright citizenship.
