yo quiero trabajar en barcelona

1. Sebastian and Tosh answered ok. 2. If you want to come to Barcelona, you better learn catalan. Spanish is not the natural language of this area of the state. (i wouldnt learn japanese if wanting to go work in China). 3. Unless you have any kind of contacts, ought to crisis, your chances of getting a job are almost 0.

Hola, se dice "Yo quiero trabajar en Barcelona". Regards, Sebastián

With my high school Spanish, I would say: Me gustaría trabajar a Barcelona. or Yo quisiera trabajar a Barcelona. I seem to recall that "a" is used to refer to being in a town or city, whilst "en" is used in reference to being in a country.
