Hi Folks,
I currently work in the US under H1B visa. I just wanted to get some general ideas about traveling to the following countries for work purpose. I have a Nepali passport and would like to know about visa requirements and/or restrictions for traveling to following countries. Any information on the easiest way to get visas would be very helpful. Feel free to add any other helpful comments (e.g one visa to fulfill requirements for two countries).
