Yes — Firefly Bio has a documented H-1B filing history: official US Department of Labor disclosure data lists 1 H-1B labor condition application (LCA) record for this employer. The most recent imported disclosure period is FY2026 Q3.
An LCA is the labor-condition step an employer must file with DOL before USCIS can approve an H-1B petition, so these rows are documented sponsorship activity — not a promise that Firefly Bio will sponsor a new hire, and not evidence that any petition was approved. USCIS decides each petition separately. Verified against official DOL OFLC disclosure data on 2026-08-09.
Green-card signal
Does Firefly Bio file PERM green-card cases?
Yes — Firefly Bio has a documented PERM filing history: official US Department of Labor disclosure data lists 1 PERM permanent labor certification (green-card) record for this employer. That is 100 PERM records for every 100 H-1B LCA records at Firefly Bio. The most recent imported disclosure period is FY2026 Q3.
PERM is the first step of the employment-based green-card process, in which DOL certifies that no able and willing US worker was available for the position — so these rows are documented permanent-sponsorship activity, not a promise that Firefly Bio will file for a new hire. Read the ratio as a comparison of disclosed filing volumes, not a green-card conversion rate: LCA and PERM are separate programs published on separate disclosure calendars, one PERM case covers a position rather than a named worker, and an employer can file PERM for workers who never held an H-1B. Verified against official DOL OFLC PERM disclosure data on 2026-08-09.

What does VisaSignal show for Firefly Bio H-1B and PERM?
For Firefly Bio H-1B research, the page summarizes imported DOL LCA labor-condition rows. For Firefly Bio 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.
