Well, the first time I a got a pass from the boss at the embassy there. They said I was missing some paperwork legitimizing the status of my school. My boss spoke with them on my cell and convinced them to let it slide. The next time I went for another school, I was missing the same paperwork. This time, they handed me a list of necessary documents and allowed me to apply for a 2 month tourist visa instead. I have that list now, but no paper work from my school. Things have much improved at Vientiane, but not at my school.
