Its the temporary licence issued mostly for 2 years. Currently every state has an exam called Fachsprachprüfung, to be cleared to get Berufserlaubnis. This exam is taken to test only and only language proficiency. One important thing to be kept in mind is that with Berufserlaubnis one can only work in a hospital as a doctor but this time is not counted in the “Weiterbildung” or post graduation. The Fachsprachprüfung exam can be taken as many times as possible. For some states having a job is a prerequisite to apply for the exam (Nordrhein Westfalen), while some can let you apply without having a job (Bayern). The document and language requirements for different states also varies, based on Berufserlaubnis. One can earn monthly 4200 to 5500 Euros per month.
