The authority, exactly
UGE-CE processes the application electronically; the decision itself is issued by the Dirección General de Migraciones (art. 76.1 Ley 14/2013). A person who already holds a Blue Card issued by another EU member state, and who has resided there for the periods art. 71 bis(4) sets, may apply for a Spanish Blue Card instead of starting from the qualification requirement below.
