hey kalovale..

i have been working using my SSN from the time i came over here in US.. after 1.5 yrs i went Nepal taking the semester break.. for three mths for dashain and tihar.. i enjoyed a lot in nepal.. there won't be any problem in the port until and unless you have the proper documentation.. in my case.. i had just had my I-20.. but to be sure i had my bank statment incase needed.. tara check chahi garenah.. they just asked us.. we were three people .. my roommates.. taking all the semester break.. the immigration officer just asked us why we were in Nepal.. and why.. name of the college and he asked whether we all are from the same school.. and he didn't ask any further question after that.. we told them that we were outside to celebrate our festival.. but make sure you take the I-20 for the college where you currently study.. don't change the college or take the I-20 where you are gonna transfer when you go to Nepal.. specially if you are taking the semester break and going back to Nepal.. ...that's all i have to say.. timro kaam gareko status le immigration ma kehi farak pardaina.. but be sure that you have atleast 6 mths ko valid VISA when you travel.. my advisor told me that even if you have 2 days left VISA for entry they can;'t reject you for the entry.. but to be sure have 6 mths of valide VISA..

hope this helps..
