I will be teaching with the AEO NIS this fall. After finally securing my official letter of employment I started reviewing the Kazakhstan US embassy's website for the visa Procedures. The process is simple enough but they do not accept applications by mail. Thinking the only way I could turn in my application I called the embassy and was told that there are private companies that can process and issue visas. Like any contractor they hike the prices but offer better service. The company I found is called US visa connection. I'll post the results when I know more.
