Currently running online magento shop in US. I have 2 language in my site French and English. I want to show the customers from France should see the French language and English for remaining countries. Is there any extension for my requirement?
I can't recommend a specific extension, but what you are looking for is some sort of GeoIP redirect. In my experience you want to signup for a proper service to get live iprange data, since these swap a lot.
Hope this helps :-)
Did you check out following extensions for internationilzation,
Here is another extension based on MaxMind's GeoIP database - https://www.magentocommerce.com/magento-connect/geoip-store-switcher-1-1.html
Allows to switch language, store, currency, tax and to block separate countries and IPs.
