Bitcoin can be owned by everyone,as long as there is an internet connection,you can do transaction with bitcoin.Even if some country banned bitcoin,you can still buy it in the big exchange.In my country,it's illegal to do transaction with bitcoin,but no stopping you to invest in it.
I think Almost anyone can have a bitcoin wallet as long as people have a computer mobile device and a decent internet connection, does the country's government mark it as legal or not.
Bitcoin is in the blockchain and it's not a special country. There is no such "state of X that is not supported by bitcoin" or something along that line.
