In our modern world, more and more people have to work in other countries, where they have to communicate in a foreign language in order to do their job or for a daily life. Although people can do it well in certain situations, I personally believe that there must be social and practical problems that have to be concerned.
On the one hand, an ordinary lifestyle requires the maximum amount of communication regularly, which most people may struggle with for bonding relationships with people with whom they live or work together. Also, cultural barriers and customs can be difficult to obtain or follow since they are totally new for people to experience in their whole life. Furthermore, without speaking properly in a foreign language, people can get isolated, and they do not feel themselves as a part of the community they are living in. On top of this, discrimination or prejudice can occur between the minority and majority, which is the main cause of most fights and discussions in many places.
On the other hand, practical problems are equally important for people who are already suffering from social problems. Firstly, navigating daily life can be difficult, from buying groceries to commuting to work by public transport. Secondly, working in an organization where you are surrounded by other people who speak a foreign language is extremely challenging, as you may face complex tasks or even some of them seem really difficult even though they are actually not. Finally, most basic needs, such as accessing services or taking education, can be difficult to gain since language comes first in these areas.
In conclusion, some social and practical problems can be faced by people since they have to work or live in countries whose languages are not spoken very well by some people.
