Your visa, salary band and layoff exposure would follow the employer of record, not the client.Most common: Mastercard · Mansai Corporation/Remote · AMERICAN BUREAU OF SHIPPINGFiles as an H-1B dependent employer.

Green-card follow-through: 0%

Of 5 labor certifications old enough to have been used, 5 expired without the employer filing the next step. Median time from filing to decision: 493 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

20 transfer filings in the last year, covering 20 workers. Median labor-condition decision: 7 days. An employer that already files transfers is one that can take over an existing H-1B.
