Prevailing Wage for First-Line Supervisors of Production and Operating Workers
Prevailing wage for Assembly Supervisor roles is set by the DOL and defines the minimum salary a sponsored worker must receive. Whether your offer uses the title Line Supervisor, Manufacturing Supervisor, or Plant Supervisor, the same four experience levels apply, and the wage floor shifts meaningfully depending on which U.S. city the worksite is in.

Level 1 covers entry-level supervisors with limited experience who follow established procedures under close supervision. A new supervisor recently promoted from the production floor, with no prior supervisory history, typically falls here.
Level 2 is the most common filing level for Assembly Supervisor roles. It applies to qualified supervisors who work independently, manage routine production issues without escalation, and hold one to four years of supervisory experience in a manufacturing or operating environment.
Level 3 applies to experienced supervisors who exercise independent judgment on non-routine production problems, train or mentor junior supervisors, and often carry responsibility for a full shift or production line with minimal oversight.
Level 4 is for fully competent supervisors with broad authority over plant operations or multiple production units. These professionals typically influence staffing decisions, own performance outcomes for an entire department, and may report directly to plant management.

Each shape is a DOL OES area, the unit prevailing wage is published for.

Verify the worksite state before comparing wages
An Assembly Supervisor offer in Lexington Park, MD clears a far higher prevailing wage floor than one in a Puerto Rico metro. Confirm the LCA lists the exact worksite city, since DOL ties the wage to that specific location, not the employer's headquarters.
Watch for bonus pay excluded from the wage calculation
Production supervisors frequently receive shift-differential pay, safety bonuses, or quarterly incentives. DOL counts only guaranteed annual wages toward prevailing wage compliance, so a base salary that clears the floor only with variable bonuses added in may still fall short.
Identify which level fits your supervisory scope
Manufacturing Supervisor roles often get filed at Level 2 even when the actual duties, managing multiple lines, handling escalations independently, or training other supervisors, match Level 3. Review your offer letter against DOL's experience-based criteria before accepting the employer's classification.

Frequently Asked Questions
How does DOL set the prevailing wage for Assembly Supervisor roles?
DOL derives prevailing wages from Occupational Employment and Wage Statistics surveys conducted by the Bureau of Labor Statistics across hundreds of metro areas. For Assembly Supervisor positions, it maps the role to SOC 51-1011 and publishes four wage levels. Employers must certify on the Labor Condition Application that the offered wage meets or exceeds the applicable level for the worksite location.
What do the four wage levels mean and how do I identify mine?
DOL's four levels reflect experience and independence. Level 1 is entry-level with close supervision. Level 2 applies to qualified supervisors working independently on routine tasks, and it is the most commonly filed level for this occupation. Level 3 covers experienced supervisors exercising judgment on complex situations. Level 4 is for fully competent professionals with broad departmental authority. Your level should reflect your actual duties, not just your years of experience.
Why does the prevailing wage for the same Assembly Supervisor role vary so much by city?
DOL uses regional Occupational Employment and Wage Statistics data, so the floor reflects local labor market conditions in each metro area. The LCA worksite rule requires employers to use the wage for the specific city where work is performed, not a national average. Industrial hubs with concentrated manufacturing demand, such as those in California or Connecticut, drive wages higher, while markets with lower labor costs set a lower floor.
What happens if an employer offers a salary below the prevailing wage for a sponsored Line Supervisor position?
An offer below the DOL prevailing wage for the filed work location creates a compliance problem for the employer. USCIS or DOL can deny or revoke the petition if the LCA wage commitment is not met. The employer may also face back-wage liability if an investigation reveals they paid below the certified rate. A sponsored worker cannot simply accept a below-floor offer and assume it will clear review.
How do I find and verify the prevailing wage for an Assembly Supervisor role in a specific U.S. city?
Use the OFLC Wage Search tool, which lets you look up the four wage levels for SOC 51-1011 by metropolitan area. Select the relevant metro that matches the job's worksite, not the employer's billing address. If you want to see which companies have sponsored this occupation before and filter by location, Migrate Mate lists employers with verified sponsorship history for Assembly Supervisor and similar production leadership titles.
