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).

UK
Germany
Netherlands
Switzerland
Belgium
France
Spain
Poland
Brazil
Mexico
South Africa

From my experience, to travel to any country in Europe all you need is a confirmation of hotel booking, flight booking, bank statement with enough funds to cover your travel expense (on average about $3,000 is recommended for visa for a week), letter from your employer confirming your employment status, travel insurance, two passport sized photographs and completed visa application paper.

For any other requirement, you can visit their website.

Can't say anything about South American countries and South Africa.
