Best visa process!
Teaching internationally can be tough with obtaining visas. Mongolia has been the least stressful visa process I have experienced.
I worked with the school in the beginning stages. They asked for typically things such as an HIV test, credentials, health/doctor recommendation, and background check. The school then processes the information for a VISA code.
For me, the wait between the Visa code and submitting the documents was the worst. I get a feeling I want to get things down ASAP. So this was a personal problem. However, the school received the code within a 2 week period they predicted.
You send the code, flight information and a money order to the embassy with a pre-addressed envelope. Finished!
Kuwait was the most difficult. Venezuela required an interview for USA citizens. China requires more now. Mongolia is the most relaxed visa process and I believe a great first step to working abroad!
