About this listing

We last confirmed this opening on Nov 2, 2026. Rates and hours come from the listing unless the note beside the rate says otherwise. Where the listing names no countries, the Africa status is our reading of it and of what is known of Alignerr's country rules, set out on its profile, and never marks a role more open than they show. The listing itself has the final word.
