FAQ
Common questions
Does Sigma-aldrich file PERM cases?
The PERM count reflects imported DOL PERM disclosure rows for this normalized employer. Raw employer names and aliases are preserved so users can inspect normalization confidence.
What does VisaSignal show for Sigma-aldrich H-1B and PERM?
For Sigma-aldrich H-1B research, the page summarizes imported DOL LCA labor-condition rows. For Sigma-aldrich PERM research, it summarizes imported DOL permanent labor certification rows. Both include roles, worksites, wage signals, case-status mix, and the latest source period.
Does an LCA certification mean an H-1B petition was approved?
No. A DOL-certified LCA is not the same as USCIS H-1B petition approval. It is an official labor-condition filing signal that should be interpreted with that limit.
Does a PERM certification mean a green card was approved?
No. PERM certification is one step in an employment-based green card process. It does not mean a green card, I-140 petition, or adjustment of status was approved.
Can this data prove an employer will sponsor a candidate?
No. Official filing history can show recent activity, roles, worksites, and wage signals, but it does not guarantee future sponsorship or predict legal outcomes.
