USA EB 3
“Skilled workers” are persons whose jobs require a minimum of 2 years training or experience, not of a temporary or seasonal nature. The skilled worker must meet the educational, training, or experience requirements of the job opportunity. Relevant post-secondary education may be considered as training.
“Professionals” are persons whose job requires at least a U.S. baccalaureate or foreign equivalent degree and are a member of the professions.
The “other workers” subcategory is for persons performing unskilled labor requiring less than 2 years training, education, or experience, not of a temporary or seasonal nature.
Third preference petitions must generally be accompanied by an approved, individual labor certification from the Department of Labor on Form ETA-9089. Your employer (petitioner) must file a Form I-140, Immigrant Petition for Alien Workers. As part of the application process, your employer must be able to demonstrate a continuing ability to pay the offered wage as of the priority date. Your employer may use an annual report, federal income tax return, or audited financial statement to demonstrate a continuing ability to pay your wage.
If your I-140 petition is approved, your spouse and unmarried children under the age of 21 may be eligible to apply for admission to the United States in E34 (spouse of a “skilled worker” or “professional”) or EW4 (spouse of an “other worker”). and E35 (child of a “skilled worker” or “professional”) or EW5 (child of an “other worker”).
