America's highest-skilled workers are being displaced from their professions by employment-based visas:

• H-1b: Congress has authorized employers to sponsor and hire foreign workers regardless of whether qualified Americans are available to fill the positions. Employers can legally force Americans to train their foreign H-1b replacements as a condition of receiving a severance package.
• L-1: Congress has authorized employers to bring foreign workers into the U.S. for one year while continuing to pay them their foreign wage level.
• PERM: Congress has authorized employers to sponsor foreign workers for green cards by simply running a few classified ads and then to find any reason possible to disqualify all American applicants.
