I would imagine for sure he no longer has that phony Dominican Republic passport the Japanese got at Narita.
And his DPRK documents, if he has them, will become invalid.
If he gets a PRC passport, I wonder what travel restrictions he will have. They will NOT want him traipsing off to Europe or US to gives at seminars entitled "Chia Pet: My Dad".
I do wonder what kind of passport his is on these days in Macao.....
