Same thing happened to one of my fren a year before. he lost his passport so he made new passport from Nepali embassy, USA. Thenafter he went to Nepal got new visa for 5 yrs and was so much happy. Unfortunately, when he landed to USA ,immigration start interviewing him and checking his all history . He had used his SSN to work for 3 months.Thenafter immigration cancelled his 5 yrs visa and send him back to Nepal. He had around 3.9 gpa and had 2 more semester to finish his bachelor degree..So, guys try to fix your problem from USA rather than goin to Nepal for VISA.
