Probably, you want to travel abroad to stay in a foreign country for a long time. Some people want to learn a language, to study in an university or just long for an experience in a different place.
Unless you are a rich person, you'll need to earn your living abroad. When arriving a new country this could be a problem, specially, if you don't speak the native language.
There are many sort of jobs as bartender, bellboy, cook,.. the list is endless. Although, you may choose to teach your own language and get some extra money. It makes no difference which language you speak German, Russian, English, French, Italian, Chinese or Japanese. There are hundreds of chances to teach languages in language schools or offering private tuition.
A part from rendering your CV in all the languages schools, you may use internet to offer you private lessons. It's free and everyone can reach your post.
Nowadays, internet provides many sites to post free adverts. Here, you can find a sample list of sites to find students for your private classes:
