Why don't you go the the USIC or whatever it is called? Sajha does not issue US visas. Each person has thier own circumstances, and each had thier own tricks up  their sleeves.

It is a dangerous thing to design your life plan based on someone else's experiences, especially when that experience comes from online ghosts.

I think the visa information leaflet clearly states that the burden is on you to show 'close ties to your native country and compelling reasons to NOT stay in USA after your intended purpose of stay there'.

Good luck
