I am new here and look for someone to help me in the registration of the university and how to study in Germany
Actually you can't submit to any college with out minimum the B1 certification.
When someone want to submit to a university he have to send them an email
And then he have to make an application for him in the university website,and then he have to send them all the papers they need and the B1 or DSH certification included and they won't accept it till all your papers are ready.
Now the thing is you have to ask about the conditional acceptance you submit for a college which accept students with no german skills. So they give you an acceptance letter, be aware that when you have this acceptance letter you van join this college as soon as you finish the language and bring the DSH or B1 or C1 for them. The problem is the conditional acceptance is MAYBE only for the students who want to come to germany to continue studying 'legal way'.
As Kenan says, there tend to be different requirements regarding German in each university, however for a basic overview of the process and requirements you can check out this website:
The website has a lot of good information: hover over "Refugees" in the top bar for a list of other resources. Specifically in regards to studying you can find a list of unviersities that offer courses for refugees are guest students (as well as a map of these Unis), official information about legal requirements for studying in Germany, and instructions about how to prepare/apply for study
By the way, would you like to stay in Kassel to study?
