Hello, I'm a student from the EU and I got an offer for a paid internship in Madrid for 3.5 months and in order to get my contract I need my NUSS, which requires a NIE as well. As far as I know anyone who stays in Spain for more than 3 months needs to get a NIE verde, however all online agencies say that NIE is enough. Which one is best suited for my case? I'm worried my stay exceeds what the (classic / white) NIE offers. (I'm not planning on staying longer than my internship period, so about 4 months max and I'm planning on renting something from HousingAnywhere if that helps).
