Living in a country where you have to speak a foreign language can cause serious social problems, as well as practical problems. To what extent do you agree or disagree with this statement?

This is my first post (as well as my first IELTS essay). Thanks in advance!

It is often assumed that living in a country that utilises a language different to our native language can result in social and practical issues. However, I strongly disagree with this common belief.

Firstly, we, as humans, have amazing brain capacity and can learn any language, given that we put in the right amount of effort and practice. Therefore, learning a foreign language is no impossible feat, especially if there is constant, daily exposure to it. For example, albeit my family is Srilankan, my parents moved to Bangladesh where my parents were able to grasp the language within several months. Of course, fluency took much longer to achieve, but they knew enough of the language to be able to communicate on a daily basis without any social hurdles or practical discomforts.

Secondly, rather than living in a foreign country being a disadvantage, I have strong faith that it actually becomes a benefit. To expand on this, my father's bilingualism was extremely helpful as a General Manager in a company that had branches in both Sri Lanka and Bangladesh. Being able to fully comprehend and translate between the two languages gave him an upper hand when it came to ensuring smooth business.

In contrast, some people disagree that no matter how much effort is put into learning a foreign language, 100% fluency is impossible. Therefore, moving to a foreign country is strongly advised against. I believe this statement to be a weak argument, not just as someone who didn't grow up in my home country, but as someone who has seen numerous people learning to communicate with foreigners with no hurdles in delivery of their messages. One such person is my sister. She is fully capable of speaking 5 languages, including Chinese and Indian. 100% fluency might not be initially achievable, but such a high level of knowledge is not required in order to get messages across to the other party, to ask for medicine in case of an emergency, and to shop for groceries. In other words, it is not essential to surviving in a foreign country without practical and social obstacles.

To recapitulate, many believe living in a foreign country brings about several issues, socially as well as practically. However, I strongly disagree because such issues are fully avoidable given that the foreign language is learned, which in itself isn't an impossible task.
