Actually, the Rohingya are stateless and don't have passports. They don't have identity cards. They used to have a temporary small white card, which has now been cancelled. They only have a receipt at the moment. The government has created a system of what they call “citizenship verification”, so that they have to actually reapply for citizenship. Initially in the documents, they had application forms where they had to put in the term “Bengali” as ethnicity, and of course Islam as religion. But because of the fact that they had to put down the term Bengali, which was under the previous government, all the Rohingya refused to participate. Now the NLD has suggested that Bengali should not be put there, but also not Rohingya.
Still, it's very interesting, because in Myanmar, generally the minorities, not just the Rohingya, have always wanted to clarify at least ethnicity on their identity cards, and of course their religion as well. As you know, in other countries.... I remember during the genocide in Rwanda, people had their religion and ethnicity on identity cards, so there was a way to identify them for killing, even. In Myanmar, it's very interesting, because some of the minorities want to be recognized. They insist on having race and religion on their identity cards.
As for passports and all that, no, the Rohingya don't have that. They have these small receipts and that's all. That's why they are undocumented.
