Welcome to WebmasterWorld Guest from 18.104.22.168
Do you know of any restriction for those kind of domain name? I didn't find anything so I suppose there are not.
Thanks for helping me.
Nic-SE is the official domain name provider and database maintainer for .se addresses. All applications must go through them. They don't sell domains, but administrate them. Use any of their domain representatives to do the acutal registration process.
I'm not 100% sure foreign citizens can register .se domains (I'm swewdish).
