Big yes in favor of the opinion that foreign language should be a part of course. there are multiple reasons for this aspect some of them are below;
first of all it is their own benefits that they must have knowledge about foreign language.it helps them not only in institute but also help them for their future tasks like immigration.if someone go to abroad for the sake of their earnings or to get higher education,it is necessary for the student to know about foreign language.because students or immigrants can express their feelings and knowledge to others by using of foreign language.
it is also important by this view that foreign language is other than your national language,so it helps to create deep vision of both national and foreign language.
different researches shows that a great number of knowledgeable books were published in English language because the number of human who understand English language is more higher than any other language although Chinese language is also big foreign language but it spreads mostly with in the boundary of china,but English language almost speaking or listening in every part of the world.
so in conclusion it is my contention that foreign language should must be part of course because it is to much important part for their better future.
