Green-card filing pattern in this occupation
Context, not a finding about this posting: of this employer's 236 green-card filings in this occupation, 97% were for a worker who already held the job.
Green-card follow-through: 92%
Of 155 labor certifications old enough to have been used, 12 expired without the employer filing the next step. Median time from filing to decision: 496 days.97% 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
69 transfer filings in the last year, covering 69 workers. Median labor-condition decision: 7 days. An employer that already files transfers is one that can take over an existing H-1B.
