Hello,

In India there are few specific languages which have a great scope like German, French, English, Japanese and chinese.

Although you can learn many more languages but these few languages have great scope as their country of origin are ready to accept you and you will get more opportunities in those countries.

You can be translator staying in India as these countries have many companies working with our companies thus giving you more scope.

You can also try for teaching stidents their basic levels as a freelancers or in big classes.

So you can go for these subjects which I have mentioned above.
