First of all, when you emigrate, you usually cannot take your friends and family with you. Therefore, many who go to live abroad feel lonely, unhappy and lost, especially before they have met new people. This may be difficult at the beginning, particularly if you do not speak the foreign language of the country where you have moved. In my opinion, the language barrier is one of the main reasons why people who live in a foreign country do not feel at home. I firmly believe that everyone who lives somewhere else has huge problems with communication almost everywhere - at work and with their new friends.
Apart from language, breakdowns in communication are caused by an often totally different lifestyle. Settling down in a foreign country can also be a cultural shock. For example, you may come to a country where the national food can taste disgusting to you. If your hosts notice your dislike of their eating habits, they may be offended. A more serious reason for concern may be a different religion - if you find it difficult to adjust to it at least to some extent, this can cause serious trouble in certain countries.
On the other hand, getting an opportunity to lead a completely different lifestyle can be rewarding experience. Seeing and feeling how others live generally makes you more open-minded and tolerant. In addition, it frequently makes you appreciate your own culture more. Meeting people from other parts of the world also helps you to realise that there can be more than one answer to the same question. To say nothing about the possibility to learn or improve your knowlede of a foreign language and its culture in the easiest and most natural way - by talking to native speakers. Finally, if you move to a more developed country, you often have better chances to succeed. As a researcher, for example, you can make good use of numerous, well-supplied libraries, and of generally better working conditions.
Nevertheless, I stil feel that living far away from home, family, boyfriend and friends can surely not as enjoyable as living in your home country. As far as I am concerned, people belong to the place where they were born. And I am not the only one who feels like that. There is another song from Kelly Familly: ''Home, nothing like home, nothing like a beautiful home.''
