The "Ban Birth Tourism Act of 2026" aims to make alien parents seeking U.S. citizenship for their children through birth tourism inadmissible and deportable. It outlines that any alien trying to obtain citizenship for a child by giving birth in the U.S. or its territories using a nonimmigrant visa will be considered inadmissible or deportable. The bill defines birth tourism as entering the U.S. for the primary purpose of obtaining citizenship for a child through birth or being likely to give birth to a child within 10 months of entry. If enacted, the act would impact aliens engaging in birth tourism by making their actions inadmissible or subject to deportation under the Immigration and Nationality Act.
