Search every Labor Condition Application DOL decided since fiscal year 2008 (the filing an employer makes to hire on an H-1B, H-1B1 or E-3 visa) by employer, trade name or job title, employer FEIN, case number, fiscal year, visa class, case status, SOC code, worksite state, minimum offered wage and decision dates. Each determination carries the employer, the job, the offered and prevailing wage, the primary worksite, the employer's contact, the attorney and Appendix A. Newest decision first, pages of up to 50. Served by Croma (`as_of` says how current the data is), brought up to date as DOL publishes each quarter.
