How this is calculated
New-employment H-1B LCAs only, the filings behind most cap petitions; extensions, transfers and amendments do not go through the lottery, and cap-exempt universities and nonprofit research organizations are left out. Each offered salary (low end of the range) is compared with the OFLC Level I to IV wages for its occupation and worksite area, wage year 2026-27; a filing with several worksites counts at its lowest level, as the rule requires. Numbers on the right are LCAs. Full methodology.
On the 2025-26 table, used for the March 2026 registration, the same offers average 1.1 entries (0% at Level IV).
