Employer immigration record

from this employer's Department of Labor filings

Green-card filing pattern in this occupation

Context, not a finding about this posting: of this employer's 35 green-card filings in this occupation, 100% were for a worker who already held the job.

Green-card follow-through: 55%

Of 20 labor certifications old enough to have been used, 9 expired without the employer filing the next step. 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

126 transfer filings in the last year, covering 435 workers. Median labor-condition decision: 7 days. An employer that already files transfers is one that can take over an existing H-1B.
