H-1B wage level

the lottery is wage-weighted — each level is one more entry

Level I · 1×
Level I$91,8741 entry
Level II$113,8592 entries
Level III$135,8243 entries
Level IV$157,8104 entries

The bottom of this range ($78,800) is below the Level I prevailing wage of $91,874. An H-1B cannot be filed below the prevailing wage, so an offer at the floor of this band could not be sponsored as posted.

Based on the DOL prevailing wage for this occupation and worksite, a base salary of $113,859 would place this position at wage Level II. That figure is within the posted range, and I'd like to target it. This role classifies under "Software Developers" for prevailing-wage purposes.

DOL prevailing wage, 2026-27 wage year · Software Developers (15-1252) · Philadelphia-Camden-Wilmington, PA-NJ-DE-MD. Wage level is derived by USCIS from the offered wage, occupation and worksite; the occupation shown is inferred from the job title.

Files H-1B transfers

2 transfer filings in the last year, covering 2 workers. Median labor-condition decision: 7 days. An employer that already files transfers is one that can take over an existing H-1B.

Sourced from Department of Labor LCA, PERM and prevailing-wage disclosure data. Employer matching is by name, so figures may be split across an employer's legal entities. Absence of a filing means none appears in our copy of the data, not that none exists.
