Inquiry about initial resedence permit application

Hi,im a 3rd country national and i submitted my initial resedence permit application (student) to the embassy since my accomodation is in Wiener Neustadt their migrstate office will handle my application.

I heard they take forever to give you a response (either positive or negative),are there any students here who had previous experiences with this office? If so How was it? Ps:i was admitted to Universität Wien preparatory course (A2 German level)
