Austria is significantly more immigrant-hostile than Germany, in terms of the burocracy - how much paperwork you have to submit, how often you need to renew your visa, down to how long they make you wait for an appointment and how (un)pleasant the government workers who are handling immigration are.

I've lived for 8 years in Austria and a bit over 2 now in Germany. The feeling I get was that the Austrian officials were constantly looking for ways to make it as hard as possible for me to stay in the country and the Germans for ways to make it easier.
