Permanent Labor Certification

Permanent Labor Certification (not to be confused with the Labor Condition Application, LCA) is a process step required by some categories of employment-based immigration to the United States of America. Its stated goal is to "protect U.S. workers and the U.S. labor market by ensuring that foreign workers seeking immigrant visa classifications are not displacing equally qualified and willing U.S. workers".
