IIRC, and remember this was two years ago, the lawyer’s point was that because Indonesia does not recognize dual citizenship, he would have had to renounce American citizenship to qualify for Indonesian citizenship before he could be issued an Indonesian passport. Ergo, if he traveled anywhere under an Indonesian passport, he’s an Indonesian, unless he was later naturalized as an American.
I’m not a lawyer, but the guy I am talking about does handle immigration issues for foreigners in Japan, or did, he’s not a close friend so I have no idea what he is doing now.
Thanks, Ronin.
