A friend of mine is being investigated by immigration. As far as I'm aware she's worked in the UK for ten years. She is employed by a reputable employer who are very strict about gaining proof of right to work. I know things will be tightening up soon and she will have to earn above a certain amount but does anyone know if South Africans are normally able to acquire work visas and do these perhaps run out after a certain amount of time. she is in a low skilled job but one which is generally filled by immigrant workers.
