As president, what was George W. Bush’s main accomplishment regarding immigration?

Bush signed the Secure Fence Act of 2006, authorizing construction of about 700 miles of fencing along the U.S.-Mexico border. His proposed guest worker and broader immigration-reform plans did not become law, and the fence did not end illegal immigration. Therefore, the correct choice is “He authorized a 700-mile-long fence along the US border with Mexico.”
