For
Knowledge of additional language gives an edge - makes a person more competitive in today's fast paced world - better employment opportunities with fluency in a foreign language - multi-national companies send professionals for on-site projects to other countries - delegates from other countries coming to interact with people of our country - can work as translators, interpreters or tourist guides, etc. - preservation of culture and tradition through native language.
Against
Students are already burdened with two languages - no need for a third language - no natural inclination for foreign language - foreign language not of much use in daily life and gradually gets forgotten - should not be forced on people who do not need it - can be taught only to those who demand for it - time and effort should not be wasted on something of no clear use.
