When my daughter decided to emigrate to New Zealand, there were plenty of people telling her she was making a big mistake (including her sister-in-law and sister), She felt some of them would have been very happy if the move had not been successful. Some were undoubtedly motivated by jealousy. Well, sucks to them! She, her husband and children have never been happier and love their new country. No, they do not hate England, but they could see very little chance of promotion for her husband and they wanted a different lifestyle. They were able to afford a lovely home with enough land to keep chickens and pigs and grow their own fruit and vegetables.
Of course, they did lots and lots of research, her husband had a very good job offer in writing and there is no language problem. The three children who went with them were just at the optimum stage of their education to make the change.
Like granjura, I was amazed at the people who were planning to move to France in May and wanted to know how to find a school for their children in September - the children never having had a French lesson in their life. They came without knowing how to source health care or benefits, how to register their car, how to let the tax offices of both countries aware of their change of residence, how heavy social charges are in France, the rules that govern letting, or running a business, employment law.........they seemed to think that becoming permanent residents was no different from spending two weeks on holiday. We heard some very sad tales of people for whom it had all gone wrong - failed businesses, unexpected accidents or illness, divorce, bereavement.... I always felt very sorry for them, even those who appeared to have failed to do the necessary research.
