Ban Birth Tourism Act

This bill amends U.S. immigration law to make certain nonimmigrant visa applicants inadmissible if their primary purpose for entering the U.S. is to give birth and automatically grant citizenship to their child. It specifically targets individuals seeking temporary visas (like tourist visas) primarily to obtain U.S. citizenship for their child through birth in the U.S., barring their admission. The bill includes a key exception: it does not apply to those seeking legitimate medical treatment related to childbirth if citizenship for the child is not the main reason for entry. The policy change would directly affect noncitizens attempting to enter the U.S. on temporary visas for the sole purpose of birthright citizenship.
