If you’re serious, I’d say language is optional in the first step - at least in Germany. If you manage to find a job here, you may get a visum (Aufenthaltstitel) for many years. A colleague of mine (IT) came here from India around 15 years ago and still only has rudimental German skills. If you want to integrate well with locals, it’s helpful of course and you also need a certificate to proof your German for permanent citizenship. But for coming here a job is far more helpful than language skills. And in many bigger or international companies English is the norm anyways.
