I am an Indian by nationality and I have completed one year of Postgraduate studies in France and presently residing in France.

I want to know how I can get French citizenship?

Many Thanks!

You could join the French Foreign Legion. Serve 12 years as a Legionaire, and you're entitled to French citizenship, and a commission in the Regular Army, (and a cool hat).

Seriously, you should contact the appropriate ministry in Paris. (Unless you're interested in the Legion idea, in which case you must report to their headquarters, which is in Marseilles.
