(handed me the printed 214(b) print out)

My parents are retired 65 + and don't have a passport. I stay with them.

I have my leaves approved for Dec end-Jan, wish to reapply again very soon.in November.. Is it possible to have the visa approved the 2nd time after being rejected 1st time? This time plan to get it applied through a visa consultant

Does having a itinerary and saying I am going for tourism, booking hotels to stay increase my chances of getting visa? Or having no travel history is the reason for rejection. (I did not ask the VO. Thought I should not question him. Its incorrect)

I feel i should have shown my payslips when officer asked do you know US is a costly country.
