Nobody wants to go back to the US. I find out very hard to believe that the embassy will grant you a letter asking for an extension because you simply "don't want to go back".
I get that part. But to stay longer there has to be a good reason. I am asking about why you have to stay longer. You didn't understand my question the first 2 times so nevermind
I understand that. I am asking the reason for asking the embassy for the letter. Do you have a medical reason or is it because you can't get a flight. Something else?
