Before moving abroad to find employment, you should dispassionately examine your motives and credentials. What kind of work can you realistically expect to do? What are your qualifications and experience? Are they recognised abroad? How good is your local language ability? Unless you're fluent, you won't be competing on equal terms with the locals (you won't anyway, but that's a different matter!). Most employers aren't interested in hiring anyone without, at the very least, an adequate working knowledge of the local language. Are there any jobs in your profession or trade in the country and area where you plan to live? Could you work in a self?employed capacity or start your own business? The answers to these and many other questions can be quite disheartening, but it's better to ask them before moving abroad rather than afterwards.
