I am a US citizen who got a residence visa for Spain. The Spanish residence visa is valid for 3 month (June 1st to Sep 1st). Such a visa allows you to go to Spain and convert the visa into a residence permit valid for one year.
I went to Spain on 1st of June, stayed for 10 days and then instead of converting the visa into a residence permit I changed my mind about living in Spain and went back to US instead. I stayed in US for 10 days and then went to Germany on a Schengen visa (so, using just my Passport).
I know that on a Schengen visa you can stay 90 days in any 180-day period in Schengen countries, but does the count start from the day I entered Spain or Germany?
In other words, can I stay in Germany for 90 days or 90 days minus the 10 days I stayed in Spain?
Or maybe, maybe I am allowed to stay in Germany under the Spanish residence visa and when that residence visa expires I can stay for another 90 days under the Schengen visa?
