“For nearly two years now, the FBI has nabbed dozens of Chinese Communist Party spies who, while posing as graduate students and research scholars at top academic institutions, siphoned out America’s most cutting-edge national defense material for untold years. The spies, many secretly members of China’s military services, had to get in close to do damage this grave and found an unguarded path through America’s largely self-babysitting cultural exchange and student visa programs

But on the eve of plugging these national security holes, President Joe Biden has canceled the repair and instead bestowed a priceless gift on People’s Liberation Army intelligence services: continued American vulnerability. At issue are the 1.5 million cultural exchange “J” visas and the student “F” visas active in any given recent year”.
