Hi, thanks a lot for you help and info Bev and Gallus (and for moving my post in a better place)!
Yes... I am totally aware of the situation is a "bit" tricky! is for this that I am trying to learn French while I am in Italy, and my comprehension is really good but I find really difficult to express myself. I thought about airport and call centres or costumer services as in Barcelona I worked with a lot of people from UK or USA that didn't speak Spanish (or little), but maybe it might be difficult in Toulouse as it's not a very big city.
I am totally ready to do other kind of jobs as waitress-cleaner, but I am afraid that they will ask me a good level of French.
Thank anyway for your support!
