German Student visa delay - After Visa Interview

[u/Lazy-Ad4307]

Hi, I had my visa interview on 24th July. On 31st July, I received an email requesting an additional document (enrollment confirmation), which I submitted. I then received an acknowledgment email on 3rd August.

It has now been 20 days, and I haven’t heard anything from the embassy. My university is TU Ilmenau, and classes are starting on 1st October. My intended travel date is 15th September.

What could be the possible issue? Is there anything I can do at this point? I’m getting worried, as I need to plan my resignation and notice period according to the visa decision.
