I wasn't aware that US/Kenyan dual citizenship was possible. My wife is from Kenya, just a green card holder at the moment, and as far as we know, she has to make an either or decision regarding that. She's been here long enough to become a citizen now, but she just has to study all the stuff for the test and then we have to fork over the money.
Incidentally, and maybe I shouldn't admit this around here, she's the same tribe as Obama's father, the Luo tribe. All the Luo people I know in the US with the exception of my wife are huge Obama fans, for no other reason than he's their tribe. Policy doesn't matter at all. "He's one of us."
But man, wouldn't it be something if there was any truth to all this stuff, or if at least his reluctance to produce documents could be used effectively?
