The Supreme Court is expected to rule on whether to uphold the constitutional protection that babies born in the U.S. are citizens. President Donald Trump's executive order seeking to end birthright citizenship was deemed unconstitutional by lower courts. If implemented, it would affect about 255,000 babies born each year over decades. The 14th Amendment, passed after the end of slavery, confers birth right citizenship to the children of immigrants, not just enslaved people. Some foreigners give birth in the US because they want their babies to obtain U.N. citizenship, but this amounts to a small portion of births annually. The Center for Immigration Studies estimates that 70,000 births to temporary visitors in 2023 will be less than 2% of the 3.5 million births reported that year.
