Thanks for the link, however, that seems to speak to someone who only put one name on their Indian passport, and the US government puts FNU or LNU. In my wife's case, nothing is forgotten or left out. She has only one name. Her Indonesian passport only has the one name. She'd have to choose to have a new name given to her (not a family name, since it doesn't exist in her village/family), and that would not be a last name either. Then change her Indonesian passport and all of her Indonesian documentation with the new added name, and THEN come back to the US after re-applying for a VISA with the newly added name.
