International Buddypress social network

I'm building a social network using buddypress. I'd like this social network to be international

I'm using Xprofile plugin to create buddypress fields. I want every new user when register, to be able to choose their country, and depending of the country, that an multi selector dropdown appear with the states from this country so that they can choose to add.

( For example I want someone from USA to be able to choose Utah + California. Or if someone is from France, I want him to be able to select 2 french states ).

I guess I need to use conditionnal field plugin to do that.

The problem is that then, I want those states to appear in the profile page. I know I need to add

" " to the member-header.php.

The problem is that this data field is gonna be different for every country. I don't know how to do that.

Any help ?
