You must admit that it is a pain that Indonesia does not recognize double nationality....I don't get it! What is it these people don't understand about Indonesia doesn't recognize dual passports? Either keep one or the other and accept that's the way it is.
It used to be like that in Thailand long time ago, and I remember being obliged to play some smart games when teavellikg to France with our kids. Lucky Thais first closed an eye on it, and then accepted it.
