The purpose of this legislation, known as the Baseball Diplomacy Act, is to allow Cuban nationals to come to the United States to play organized professional baseball without facing certain legal restrictions that currently apply due to U.S. embargo laws against Cuba. The act aims to facilitate the participation of Cuban players in Major League Baseball and promote cultural exchange through sports. Key provisions of the act include the removal of specific legal barriers that would normally prevent Cuban nationals from entering the U.S. for baseball.
