(CNN) An upcoming change to State Department visa guidelines is expected to take aim at birth tourism, the practice of foreign nationals giving birth on US soil to ensure their children become American citizens, according to a State Department official.

The State Department official told CNN that the department is amending a regulation to ensure that visitor visas to the US are not used for birth tourism. The rule will be "published shortly," according to the official, who said it is intended to address the national security and law enforcement risks associated with the practice. Details about the change, how it will be enforced and the impact to travelers were not immediately available.

The Department of Homeland Security and White House referred CNN to the State Department for comment.

Axios first reported the expected change.

The expected announcement comes a week after a Hong Kong-based airline apologized for demanding that a passenger take a test to prove she was not pregnant before boarding a flight to the US Pacific island of Saipan -- part of the US commonwealth of Northern Mariana Islands, which has emerged as a favorite destination for "birth tourism."
