There are many ways to improve your German. For example, you can practice with various online offers, here are a few examples:

Deutsche Welle

„Ich will Deutsch lernen“

Alumniportal Deutschland

German for Refugees

You can also visit so-called "language cafés" in your area. Refugees, migrants and locals meet there regularly to practice German together. They talk about different things in a nice atmosphere. An example of this is "Café Welcome" JUZ Mannheim, which takes place every Wednesday from 3.30 p.m. to 6.30 p.m.

Another possibility is a language tandem partner who is just learning your mother tongue. For example, you meet for coffee and speak half of the time in your mother tongue and the other half in German. This way, you help to improve each others' language skills.
