“If Obama was adopted by Lolo Soetoro, and neglected to file the appropriate paperwork in 1979, he’s still an Indonesian citizen.”
File the appropriate paperwork with whom?
The United States government — specifically the INS.
OK. Let me get this straight. Your assertion is that it is possible for someone to file "paperwork" with the United States Immigration & Nationalization Service that, once executed, would somehow sever or undo any citizenship bestowed upon them by another country. Is that correct?
That my friend, is a fascinating interpretation of US and international law. Fascinating.
