I am on a Blue Card since 2017 and have applied for the Niederlassungserlaubnis in October 2020 in Germany. Authorities reached out to me in January 2021, saying that the minimum threshold for the required salary has increased in January 2021. My salary is now less than that minimum. I need to get an increased salary to qualify for the Blue Card. It's strange.
My questions are:
Since my Blue Card has already been issued in 2017, why do they need to reevaluate it? Technically, I am Blue Card holder.
Even if they have to reevaluate, I already applied in 2020 when my salary was as per requirement. They started processing in 2021. That is not my fault, correct?
Has anybody else experienced this? Any advice on how to proceed?
