»The Labour Market Opinion - A Central Regulatory Tool in German Labour Migration Law«: The Labour Market Opinion has been a central regulatory tool to determine whether to grant a residence/work permit over the last 50 years. Only if a German, EU citizen, or a foreigner granted full labour market access is unavailable for a position offered to an applicant, the permit can be granted. In light of its scope of application decreasing in recent years, this book critically examines the extent to which the Labour Market Opinion still has a place in modern German labour migration law.
