This question already has an answer here:
I have Polish National Visa valid for one year. D type, multi entry. But I haven't gone to Poland yet, because I had to go to one project, which got rejected its financial part, so I didn't go there yet. But I have a project in Italy for one week in April. I can't apply for italian visa, because they can't give me any, if I have already valid visa for Poland. So my question is can I have my first entry to Italy with Polish National Visa. Can you please give me information regarding this?
