Before your employer files your H-1B petition, they must get a certified LCA from the Department of Labor. Here is exactly what that document means and what protections it gives you.
The Labor Condition Application (Form ETA-9035E) is a document employers must file with and get certified by the Department of Labor before USCIS will process an H-1B petition. Its purpose is to protect both H-1B workers and U.S. workers from wage depression.
Congress created the LCA requirement because H-1B workers have historically had limited bargaining power, their immigration status depends on their employer, making them reluctant to complain about wage violations. The LCA creates a legal obligation on employers that DOL can enforce independently of the worker.
DOL sets prevailing wages at four levels (I through IV) based on the position's SOC code and geographic area. Level I is the 17th percentile of wages for that occupation, entry level. Level II is the 34th percentile, experienced. Level III is the 50th percentile, fully competent. Level IV is the 67th percentile, fully competent senior.
Employers must pay AT LEAST the prevailing wage for the level they select, AND at least the actual wage paid to similar employees. If they select Level I but all their comparable employees earn at Level III wages, they must pay Level III. The LCA level affects your immigration file permanently, it is public record.
If your employer violates the LCA, pays below prevailing wage, benches you without pay, deducts wages that reduce your pay below prevailing wage, you can file a complaint with the DOL Wage and Hour Division. DOL investigates independently and can order back wages, civil penalties, and debarment from future H-1B filings.
DOL complaints are more powerful than USCIS complaints for wage violations because DOL has direct enforcement authority over wages. You do not need to be in valid H-1B status to file a wage complaint, former employees can file up to 12 months after the violation.
