I'm a student and working part-time in a company as a developer. The company policy is that when someone graduates then they might ask them to join as a full time employee. Recently, the majority of the students have been asked, but my problem is that I don't speak German very well so I'm not sure about my chances. I am working here for 1 year and will graduate in about 3 months. As I am non-European and have visa conditions, I can't wait for their answer until graduation.
I wanted to know what is appropriate way to ask my manager for full time employment.
