Nepalisathi, nobody's gonna reply to you this late except the ones awake like me! Here's the thing! Now that your Passport is gone, you're gonna need new visa to come back to the states ( if you were to leave the U.S. ). As long as you stay here and attend a college,you're fine! You'll be issued an I 20 and you don't have to worry about anything else! As far as the SSN is concerned, make sure that you contacted the nearest SSN office IMMEDIATELY! Sorry about everything else! Feckin chor bhates haru foodstamp ma banchna bahek aru kehi garna sakdainan!
