I don't know the details, but I could imagine they would prefer to not know that he is a Pakistani citizen. In that part of the world, citizenship and identity can be a messy subject. None of those countries is ethnically or linguistically homogeneous, not all of them can reliably track all citizens if they lost their papers. And I can imagine he wouldn't be a "gift" for the Pakistani government itself, considering political implications.
