Do I need a copy of my Laos visa for an education visa application in Vientiane?

At about 8:00am they opened the gates and let people come inside. Because I was one of the first 150 or so I was able to get a seat ( other people had to stand ) and wait until they started accepting visa applications at 8:30. After I submitted my visa application and documents from my school I was given a number and had to wait to be called so they could ensure I had all the correct paperwork. After my number was called they told me i could come back and pick up the next day at 1:30pm. Total time for the first day was about 2 hours which wasn’t bad

A lot more people behind me now
