Black or...

I was told that according to the docs, Romanian people have got the first place in ranking of immigrants to Spain, reaching to a record of 450,000 in recent years.

And last week, the media announced that in a one-day mission in a centric street of Barcelona (Raval), 110 people were arrested as they have been involed in prostitution. They also said that most of these people are coming from Romania and disturb the society with such activities making the city unsafe especially for those who live/work nearby.

I'm not sure if prostitution is banned here coz they held an international festival here in Barcelona (2 months ago). Also, they are freely moving in other areas of Barcelona publicizing their black-job.

Good or bad, banned or permitted, the point is that they get here easily perhaps without any problem. But if you are, for example, a well-educated one and want to do some scientific work here, then you have to follow a long procedure to get the work permit which is sometimes impossible.
