If the salary of a future employee (also happens to be a skilled worker) in Germany already qualifies for Blue Card, can the employee still get Advance Approval according to § 81a AufenthG for fast-track procedure, or is this procedure valid only for those employees (also happen to be skilled workers) whose salary is less than what qualifies for Blue Card?
Although I couldn't find this in official documentation, through communication with many people online, there is this confusion that fast-track procedure is for only those skilled workers whose salary, as of when they apply for visa, is less than what qualifies for Blue Card.
More information about the fast-track procedure can be found here and here.
