An entry visa is normally valid in all the Schengen countries. In exceptional cases a visa may be granted solely for entry into the country that issued it. As Spain does not recognize passports issued by Kosovo, Schengen visas issued for citizens of Kosovo are valid for all Schengen countries except Spain. However, note that the border police might require information on the purpose of your visit when you enter Schengen. A visa is not a guarantee that you will be allowed entry to Schengen, the border police always decide whether or not you will be allowed entry to Schengen.
In most cases, the Embassy of Sweden in Skopje decides whether to grant a visa. If the Embassy for some reason is unable to make a decision in a visa case, there is a possibility for the Embassy to pass the case on to the Migration Agency in Sweden for a decision.
