Median time from filing to decision: 496 days.100% of their filings were for a worker who already held the job.Only certifications past the 180-day window are counted — recent ones cannot have expired yet.

Files H-1B transfers

70 transfer filings in the last year, covering 70 workers. Median labor-condition decision: 7 days. An employer that already files transfers is one that can take over an existing H-1B.
