We set sail aged 28 and 33. We had to wait until my OH had 6 years work experience in his role to meet the visa conditions to apply. As soon as he had the 6 years we applied and as soon as the visa came through we got the wheels in motion to go. Our property settled on the Friday lunchtime and we left the UK on the Monday! We were keen to get over here and start building a new life. To me you either want to go or you don't, everyone is usually in the same position we all give up jobs, homes, cars, friends, families and a life that is comfortable and familiar and take a leap of faith coming over here. We sold our property just at the right time and despite a friend in the UK predicting that property prices were going to double in the next 5 years (I think they must have been living in a different place to the one I was living in!!!) and people saying "are you going to rent your property out just in case you don't like it", we sold up lock, stock and barrel, selling most of our furniture to the lady that bought the property and we took the equity and ran! The property market crashed not long after we left and has continued to struggle. Nearly 7 years later, we could go back and buy our UK property for a third less than we sold it for. Thank goodness we didn't hang around.
Everyone is different and I am not saying it is the case with everyone, but some observations I have made is the older someone is the more 'successful' they might be in their career. This translates to a higher salary, perhaps a company car and the lifestyle that goes with the higher salary. Some people (not all) then find it harder to come over here and start again and they may have to take a step back in their careers. People often say they are prepared to do anything, but the reality is often not the case and it can be very demotivating for people. If you come when you are younger and perhaps not so further along in your career it can be an easier transition as there are more jobs at this level than at management level. On the flipside I have met people that were working at a higher level in the UK and genuinely have no desire to work at that level over here and have had career changes and are very happy.
