If you are a citizen of one of the 62 nations covered by the Schengen visa regime and you are visiting Spain for the purposes stated by the Schengen visa, you do not need to apply for a Spain Schengen visa. It should be noted that if you have previously been refused admission into the Schengen area without a visa, you will still need a Schengen visa in order to visit Spain, even though you are a citizen of one of these countries.
Spain long-stay visas - for staying in Spain for longer than three months. Whether or not you can work in Spain will depend on the type of long-stay visa you apply for.
