if you're in f1, if you denied then you come back to f1, but your future green card or h1b process will be difficult. if you leave the usa and try to come back IO at the entry port don't look at you like you have true student intentions. if you drop your status then you can go to court and have higher chances of getting approved,  but if denied then you have to leave the country, unless u find some us citizen to marry and io buys your story. i think laltey with high numbers of Nepali asylum things are getting complicated for nepali asylees. i know lots of Nepali asylees whose green card is pending for years. watch out..
