I have come to Poland to study in a university. I have a Type-D National Visa.
I am actually planning to move to a university any other country in Schengen. If I cancel my admission (this is needed to get back my tuition money that I have already paid) in the polish university before I get the acceptance letter from my target university, will I be able to stay in Poland until I get acceptance?
will I be staying with a threat of stripping my visa off?
What is the rule?
