I know two people that have recently moved to Switzerland and have no intention of going anywhere now. I think once you settle it’s a nice, calm life.
I’m currently in the process of getting a sponsored visa for Australia. At this point I have more family in that country that anywhere in the world. I was in Sydney in May and even managed to get an overnight trip in to see my brother on the Gold Coast on one of the weekends I was out there.
Depending on what skills you have, it’s not a bad idea to go the sponsored route. If it doesn’t work out and you don’t like the place, then chances are your employer will have footed the bill for almost all of it and you can go back home with no regrets or money spent. If you do like it, then it’s easy to convert that into permanent residency. I realise it’s a bit far for a lot of people that aren’t used to being on the other side of the world to their parents, etc.
