Once money has been paid to bring said cousin into the UK
i speak from direct experience. Neighbour married cousin in Pakistan. Brought him over then left him on his own whilst she lived with family. He used to tell me all about it. His sister married her brother at the same time so two were brought over.
he used to use my landline to call his family in Pakistan (paid me). He told me his father had paid a lot of money for them to marry the two cousins and bring them over.
i’m not racist, I’m telling the truth. If some don’t like it that’s their problem. There’s a hell of a lot more I could tell but I was given a lot more insight into the culture and practices than most people. Some of it shocking.
