I am from Vietnam and a full time student in Finland.
I have finished my internship in Germany in January 31st 2015, and my working visa for internship ended on that day (saying also I have 7 more days until I have to leave Germany).
However, I obtain a student residence permit in Finland until August 2015, therefore I decided to stay and travel within Germany from 1st of February until April 20, 2015 (I have the right to stay in Germany for 90 days maximum).
Could you please explain to me clearly about the 90/180 days rule that I have to apply in my case? And after April 20, 2015 I will travel outside EU until May 11, 2015. Then I will come back to Germany for a while before I fly back to Finland for my study.
I would like to ask, how many days left I have to stay in Germany after May 11, 2015. Does 90 days authorized start counting all over again or it keeps counting within the period?
Could you give me some advice in my case at the moment so that I can book the ticket to Finland from Germany after May 10 , 2015?
