Ok I have not gone through any of the comments given by ppl above as i dont know they have been through the same situation but i have been so here is my case and hope this will help you:

Sold tobacco to minor while in F1 status during police sting operation
Took my licence number and gave me ticket to appear before court
Appeared in court and pleaded guilty paid fine
At the time of going nepal i became tensed because of this problem so i conducted my own background check online throug USSearch
My record came out to be clean
While coming back due to some other reason (not this case) i was taken to secondry inspection and my ssn was enterd in system
Nothing came up...So be sure to do your own background check after this case is done...if its clean dont worry..if not try to expunge it if it is allowed in your state...it will hide it..or ask if you can take any community service thing to make your record clean..in my case they didnt say me anything about class and in my state expungement of this offense was no available...

Hope this helps.
