AS A RESULT
When you move into an unfamiliar environment, your old habits are uprooted which in turn leads to a very disturbing inadequacy. This may cause psychological uncertainty, really tough to face in an unknown culture where no one seems to respond the same way you usually do.
Due to these overwhelming feelings, up to 50% of overseas placements fail or end precipitately.
Spouses may be at loss too, struggling to adapt. Kids have to meet new friends and accept a new way of interacting. It also means career changes for some and definitely facing a new mentality at work.
Expat divorce rate is unfortunately much higher than average.
BUT there is a whole different and happy side of expatriation depending on how you approach it and feel supported.
