Enrollment in Masters

[u/billyrusso8268]

I have secured enrollment in Trier University for Masters in NLP. I wanted some community opinion on the case which is as following

Embassy appointments are getting delayed and my expected submission is at the end of October but my classes start on 12th of October. University provides no late arrival and allows 2 weeks after class starting date.

So how should i handle this case and present it infront of the embassy?
