I think the advantages outweigh the disadvantages, because they may gain new experiences, learn about a new culture or language. However, they may miss their families or have difficulty to find suitable dishes.
On the other hand, if people move abroad to work or study, they may gain new experiences. And they can also travel around the country, which they visit, and they can learn new language or about new culture. In addition, I think many people move abroad because of high salaries, in abroad they may earn more money instead of working their countries. As a result they can improve much better their quality of life.
On the other hand, moving abroad can also have some disadvantages. People may miss their families and feel lonely because they have to live far away from their close ones. They may also find it difficult to adapt to a new culture and different types of food.

Therefore, living abroad may sometimes be stressful and uncomfortable, especially at the beginning.
In conclusion, in recent years many percentage of people move overseas to work, instead of working own country. They move abroad because of high salaries, they can improve their life quality. However, they may miss their families or have difficulty to find suitable dishes. I think, despite these demerits, merits overweigh disadvantages.
