Hello dear Musawvir,
thank you for sharing your question in the community,.
As far as I am not only a mbeon migration councelor, but a language teacher too, I can share you the following informations.
First of all, you are not commited to attend an integration course, but you are commited to get B1 German level. But if you want to keep your jobs, you can do the following things:
1. Search an evening course. The Volkshochschule offer courses in the evening twice a week. There you can start from A1 maybe even to B1. You need to search for information in your region.
2. You can learn alone, using an application for your smartphone or online on your PC if you have one. The application you can download free charge from Google Play or App Store. Here are the download links:
I hope that these infos can help you. Please contact me if you have other questions too. You can contact me through the mbeon application. You can download it free charge. You can do this using one of the following links:
The app and the messaging are confidential.
You can find me in the app under the name: Alzey, Herr Zsigó.
Thank you for your trust.
