@ S_man23: No I do not have visa stamp in my passport and I am planning to travel somewhere around November. I am also planning to appear for visa interview in US embassy of Nepal. As you know there is no guarantee of getting visa stamp from Nepal. So, I'm trying to perp myself for the worsted case scenario. So, If I come back to USA in advance payroll, I can get back to my H1B once I am here in USA right ?
