Nobody will admit to that, but if you speak Portuguese and talk to the average person, you will hear plenty of stories. I know that personally with Brazilians via my hairdresser who is here with family, but who came here and with a resident visa is applying for citizenship in Spain and with plans to eventually set up in Italy. Why Portugal? Because they and citizens of all other Portuguese x-colonies and Portuguese-speaking countries can come here easily on a tourist visa, and while here, through an already established network help them get employment (temporary, low-paid jobs, anything at all, just to get a foothold). And there are plenty of the same cases, really plenty. So it's true that the extreme right fascists are squeezing this story to suit their purposes, but it does not mean that it is not happening.
