Is there anything in immigration law in Germany which enforces that a family re-unification visa process should be finished maximum in a defined interval?
I am from Afghanistan and having EU Blue-Card. My wife and children applied for the appointment in German embassy on March 2021, now it is 7 months the embassy didn't gave the appointment for interview and they are telling it will take about two years to reach my wife's turn.
In this case, do I have the right to challenge this decision of embassy or any law which regulate this?
