Hello Siva,

Unfortunately I cannot answer your question to the full, however I can tell you what is important for the Niederlassungserlaubnis. Apparently it depends a bit on who your case officer is, however it is always advantageous to show them a "secure future". So, for example an unlimited contract is a huge advantage and a one year only contract is a disadvantage. Some officers are quite lenient and are okay with a recommendation letter from your boss and a one year contract. In your case, I don't know what happens, but they may see you as a person with unclear future. Again, I think it depends. If you can do that, try to show them some solid contract and not HiWi-like jobs or part-time jobs. If you can't, then I think you have to apply with what you have and maybe you can get a reference letter from your boss. That may improve the situation.

This is what I think, I'm sorry that I don't have a full answer. Good luck.

1. Do you have a degree from a German university?

2, Did you quit your job effective December 2015?

In order to be eligible for an NE under §18b you need a degree from a German university AND must be currently working at a position suitable for someone with a degree (manual labour is not sufficient).
