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 41 green-card filings in this occupation, 95% were for a worker who already held the job.

Mastercard Technologies, LLC obtained a prevailing wage determination for Software Developers in O'FALLON, MISSOURI on 2026-06-18. No matching green-card filing appears in our data yet. The determination expires in 10 days (2026-09-15), and a green-card filing must follow before then or the employer starts over.+1 more active determination on file

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.

Sourced from Department of Labor LCA, PERM and prevailing-wage disclosure data. Employer matching is by name, so figures may be split across an employer's legal entities. Absence of a filing means none appears in our copy of the data, not that none exists.
