Greetings!!

It totally depends upon you as in which country do you want to work because learning French is definitely good it is one of the most useful foreign language and will help you to work with clients from the other nations however it won't be completely applicable to use the language you learnt in India, since majority of your clients are still going to be Indians also if you wish to work internationally then learning French will benefit you since you will have edge over other competitors who wish to work abroad but aren't fluent in French or any other foreign language, thus from future perspective anything you do or any skill you learn never goes waste and is beneficial in one way or the other.

All the best!!!!
