living in a foreign country where you have to speak a foreign language can cause serious social problems, as well as practical problems.

Languages in the world are only the way for effective communication, so it’s important to know about the

language

of the

country

where you are living, to express yourself and understand others in an effective manner. In my opinion, if you don’t know the

language

or only have some basic idea,

then

that could have a negative social impact and cause serious practical problems. Today we are living in a more socialized kind of world, where we come into contact with different people of different nationalities and cultures. So, it has become important than ever to know the

language

if you are living as a foreigner in another

country

, which is not your home

country

. Another reason you should know the

language

is social, which is the most important factor. If you are not able to socialize with the local people because of your weak command of the

language

then

it could have negative consequences, which would be limiting your ability to mix into the society and

hence

you would lose the chance to become an important and valuable member of that society. The

second

reason as it is raised in the question, that there are some practical issues

also

, which can fail a person in becoming successful,

for example

, if a person wants to do some job in a particular field and due to the

language

deficiency he is not able to communicate well, so that would limit that persons ability to find a good job and ultimately become a burden on the community, as well as on the

country

, where he or she is living. I know one of my friends had

this

issue, he moved to one of the European countries for a better future, but when he reached there, he failed in learning the local

language

despite trying very hard for a long period of time and came back home. Whereas, I know another person who was from the same nationality, he learned that

language

very quickly and now he is a respectable member of the society and he is working in a private sector. So the conclusion is that

language

is the key to success if you want to succeed in a foreign

country

.
