I would like to revive this thread, as I do not see anything that applies to my case.
I received my first B permit after 2 years with L ( I am a non-eu with unlimited contract). Here is my case:
-My permit card does not state the name of my company anywhere
-Neither my permit card nor my "stellenantritt" paper have the words "stellenwechsel nicht moeglich".
-the "stellenantritt" paper has the words "Frist Zur Ausreise" before my title and company name. (is this important???).
the permit has a duration of 1 year, renewable up to 36 mo. from Einreise.
