. Since you mentioned that you are now in Community college, I am guessing that when you first arrived in the US, you got the visa by using some other "better" university's I-20. If you then transferred to a community college from your original university, then your visa is "technically" not valid.

If you still have the previous unexpired visa, then you can still take your chances and go visit Nepal. BUT, if they stop you at the airport in the US on your return, they have the authority to ask you to show your I-20, then you are in big trouble.

Every time an international student wants to travel to Nepal, they have to get their I-20 signed by the International Office personnel. If the immigration officer in the US airport notices that your visa is issued to your previous university, but your most current signed I-20 that you are carrying is from a community college, then this disparity will allow him to stop you from entering the US. They will put you on a plane back to Nepal right there from the airport.

Be very careful. Do you really have to go back?
