How to use this
Find the level that matches the experience required for the role (be honest — it sets your floor), then compare it to the salary you’re offered. If your offer is below the level that fits the job, that’s a negotiating signal — and for H-1B/E-3/H-1B1, paying below the prevailing wage violates the LCA the employer signed.
