So what? All H-4s are working illegally under Title 8 of US law if Americans are unemployed. Right now 2,000,000 American tech workers are unemployed. Possibly more. Americans are dying because of the H-1B/H-4 job robbing visa programs.
The H-4 program was never even passed by congress – it was mandated by Obama by executive order.
All of these H-4s are working illegally in America.
