Hey again. I was looking into what Saffy85 mentioned of having a working holiday visa, but apparently that doesn't apply to me. This visa is only handed out to certain countries, which doesn't include my 2 nationalities (USA and Spain).
Upon looking at the different visa's however, i saw the General Cultural Activities Visa, which would provide me with 6months - 1year stay. This way I could probably buy my return ticket for the 6months later, and then maybe get a working visa while I'm there. I'm not sure what the requirements for this are, or whether I'm allowed to work part-time at all with such a Visa.
