Cute idea at the core.
Agree with variable. The next take can create more of a mental picture of what the protag does most of the story. The specific antag and conflict.
Why does a prince have a bureaucratic issue? Being spoiled means his family has money so both his desire for the money and the problem getting it can be stronger.
Why does he try Americans? Is there a specific person he feels most confident about and spends considerable time with?
Stakes are needed that are more than money. If he's legit, it can be money for, say, a school.
It's not clear, but this seems to? be an attempt at "The Nigerian Prince Who Cried Wolf." If yes, would it be better if he starts as a scammer? He could be, for example, a poor prince or the black sheep in the family. Or a regular guy who discovers he's of royal blood.? Still hard to see what would happen in most of Act II...though if he starts as a scammer, the natural path is that he connect with one of his victims.
The potential is there, curious to see where this goes.
