I enetered USa with student visa in 2001  and left my college and worked in differnert places till 2007 and came back to Nepal with my own decision. I now repent of leaving college in first hand and  regret coming back to Nepal. I did try to adjust to my home country but nothing came good in my way. Now I have decided to apply for a visa once again ( try my luck). Back in the states I was issued a SSN also and I worked using the SSN.  All kinds of feelings running in my mind. I would appreciate any suggestion that might be helpful for me.
1. Is it a good idea to apply for a visitor visa or wht should i apply for ( my age 39) 
2. What documents shoulds I furnish to apply for B2 visa
3. Should I mentioned my SSN and DL in my visa application form
4. Is it just waste of application fee viewing my scenario

Thank You all
