Nowadays, to work in abroad many people go there with their families. I think disadvantages are likely to outweigh advantages.
On the one hand, living in overseas countries can assist learning a new language for both children and adults. Having studied completely one foreign language in other countries which are not English or other language speaking countries, they can not utilise it practically since there is no appropriorate environment for it. However, in abroad people can use language which are already learnt. One of the advantageous aspect of living in a foreign country is the quality of life. As we know countries like America, Great Britain can provide with a high-quality of life due to its amenities such as commercial and healthcare facilities for people because they developed more rapidly rather than other countries of the world.
On the other hand, it seems to me that there are drawbacks of this idea. There tend to face problems for people especially children if they do not know any foreign languages. It will lead to not socialise with others effectively and also this cause a homesickness. Another disadvantageous side is that other cultures can affect the behaviour and worldview of young people. Every culture differs from each other because of its custom or attitudes. In some countries, there might be no respect for older people or have various thoughts about the world.
To conclude, dwelling and working in overseas countries have upsides oh the sphere of study and the quality of life. Not knowing language and affects on children’s behaviour are the downsides of it.
