The strange thing is that it is newly arrived migrants who are calling for a cap on primary immigration.They have their ear to the ground and know how thousands of other immigrants are abusing this countrys kindness by exploiting the benefits system,the students programme and the unskilled labour market.For example at present a domestic worker(another name for skivvy,cleaner or maid)who lives and works continously in the UK for 4 years can apply for indefinite leave to remain in the UK followed by a later application for citizenship.Plus they are then allowed to bring their partners dependant children under 16years and any aged parent who would be left behind in their home country without family backup.
So its not just one person applying to stay in the UK.. that person is acting as a catalyst for their whole family.Way back in the 70's one Asian managed to bring in close to 70 alleged relatives by this method(over a course of few years).
Yes we need the workers but keep them on an annual review basis and don't allow them to bring in their spouses who are also allowed to work.I could go on for ages but have to do my morning chauffuering of the girls.
