I am guessing, reading between the lines, that this is about Haitians, whatever they may say. A while ago they had the "Regularization" process, which was supposed to resolve the problem for those who were here working and behaving well. However, in many cases this has been a failure and I can give two examples.
I helped my gardener obtain Regularization. It was a very tedious and expensive process but we got there in the end. He received a visa stamp on his passport and in time was supposed to get a Cedula. This never happened and now his Regularization visa has expired. He has payed someone to help him get a cedula but this seems to be going nowhere.
Another Haitian I know actually received his cedula after Regularization. He said it cost him 28,000 pesos, which sounds about right. A couple of months ago his bank stopped accepting it as ID, saying the cedula had been cancelled. He had not had any trouble with the police so there was no reason for the cedula to be cancelled. I suggested he went to the Immigration office to find out what had happened but he didn't want to go in case he was arrested and deported. Now he has been picked up in the street and has, indeed, been deported.
