Green-card filing pattern in this occupation

Green-card intent detected

Green-card follow-through: 75%

Of 16 labor certifications old enough to have been used, 4 expired without the employer filing the next step. Median time from filing to decision: 451 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
