They have an international version that does not ship with encryption of the data stored on the device, to deal with the various laws around encryption in other countries. However, there's no hardware difference, and since it's all open-source, there's nothing stopping you from loading the "US" firmware on the "International" version.
I think for international customers it's better to buy a working product with international support like yubikey rather than a crippled product like this.
