U.S. law provides employers with several limited ways to bring foreign workers into the U.S. on a permanent basis. Employment-based immigration visa categories generally have limited and static numerical caps. In addition, before petitioning for a foreign worker, an employer is often required to obtain certification from the Department of Labor (DOL) that there are no U.S. workers available, willing, and qualified to fill the position at a wage that is equal to or greater than the prevailing wage generally paid for that occupation in the geographic area where the position is located. The purpose of this restriction is to demonstrate that the admission and hiring of foreign workers will not adversely affect the job opportunities, wages, and working conditions of U.S. workers.
Permanent Employment Visas:
A Green Card Employees or Permanent Employment Visa allows a foreign national to work and live lawfully and permanently in the United States. Lawful permanent residents are subject to fewer restrictions than temporary workers (non-immigrants), and generally, may apply for U.S. citizenship after five years. In most cases, the individual’s employer must file a petition with USCIS. If the individual is already in the U.S. on a temporary visa, he or she may apply for “adjustment of status” to permanent residence after USCIS approves the employer’s petition. If the individual is outside the U.S., or is in the U.S. but chooses to have the immigrant visa application processed abroad, then the immigrant visa is processed by a U.S. consular officer.
Because of numerical and per-country limits (detailed below), some individuals must wait a significant period of time to apply for “adjustment of status” or an immigrant visa even after the petition is approved by USCIS.
“The Department of State issues a monthly visa bulletin, summarizing the availability of visa numbers for each preference category on a per-country basis. While some visas are “current,” allowing the individual to immediately apply for permanent residence, other categories are considerably backlogged, requiring the applicant to wait years.”
The overall numerical limit for permanent employment-based immigrants is 140,000 per year. This number includes the immigrants plus their eligible spouses and minor children, meaning the actual number of employment-based immigrants is less than 140,000 each year. In addition, each country is limited to 7 percentof the worldwide level of U.S. immigrant admissions, otherwise known as per-country limits.
The 140,000 visas are split between five preferences, detailed below:
