Absolutely. That leads to a situation where people may be forced to make a choice between their family in their host country and their family in the UK. Very often we are talking about people who need to come back to the UK to look after elderly parents.
I can give you a specific example very quickly. Let us call her Nicky. She lives in the Netherlands, where she looks after her husband who has multiple sclerosis. In the UK she has parents in their 80s getting older who will need care, and she is an only child. What does she do? She cannot come back to the UK, because there is no way, as a carer, she would earn the amount required in order to bring her husband. She cannot bring two very elderly parents to the Netherlands, because they do not speak Dutch. She is stuck. She has to make an impossible choice.
