— New Z and Y visas would not take effect until the Department of Homeland Security had met new border security and immigration enforcement conditions, including: expanding the Border Patrol to 18,000 agents; constructing 200 miles of vehicle barriers and 370 miles of fencing along the border; deploying four unmanned aerial vehicles and 70 ground-based radar and camera systems along border; establishing a secure identification system to verify workers are eligible for jobs.

— Employers would have to use a new electronic system to verify new hires are eligible for work within 18 months. Three years after that, all employees would have to have ID verified through the new system.

— The current green card system would be replaced by a new point system, with applicants getting credit for English proficiency, job skills, education and family ties. Spouses and children of U.S. citizens could still qualify for unlimited number of green cards. Parents of U.S. citizens could get up to 40,000 green cards per year. Spouses and children of permanent legal residents could get up to 87,000 green cards per year. About 380,000 green cards would eventually be issued via point system.

— Total number of green cards issued per year would be about 1 million, same as current law.

— Agricultural workers could get new Y-2A visas good for 10-month stays in the United States every year.

— Undocumented immigrants under 30 who came here as children would be eligible for green cards within three years.
