Does L-1A lead to the green card?

Answer

Yes, via EB-1C (multinational manager/executive). EB-1C has the same base requirements as L-1A — corporate relationship, 1 year at parent, executive/managerial role on both sides. Typical strategy: L-1A for 12-18 months, then I-140 EB-1C + I-485. Total L-1A → green card: ~3.5 years, no backlog for Brazilians.
