U.S. Sen. Mazie Hirono is co-sponsoring a bill to allow children adopted internationally by American parents to receive U.S. citizenship.

“Due to a loophole in the Child Citizenship Act, thousands of internationally-adopted children, who were raised by American parents, have been denied the same rights of citizenship as biological children,” Hirono said in a press release.

The bill, known as the Adoptee Citizenship Act of 2019, would apply to adoptees who were 18 or older and thus excluded from U.S. citizenship under the Child Citizenship Act of 2000. That law extended U.S. citizenship to adoptees under the age of 18 in February 2001.

Hirono said in a press release Wednesday that lack of citizenship has made it harder for adoptees to receive financial aid, get driver’s licenses and sometimes even led to deportation.

This is the third time Hirono is co-sponsoring the bill. Her co-sponsors include senators Roy Blunt, a Republican from Missouri; Susan Collins, a Republican from Maine, and Amy Klobuchar, a Democrat from Minnesota.
