What are the requirements for obtaining a Non B visa in Savannakhet for a work permit application?

[Non B Visa Savannakhet- Requirements]

Good afternoon

I will have to travel to Savannakhet in a week or so to get a Non B as part of the application process for a work permit. My school are currently sorting the paperwork and are awaiting a letter from the M of E apparently.

Is there anything else other than my passport I need to take? I assume I will also need photos and my original degree certificate which I have.

I saw someone refused at Vientiane fairly recently and want to ensure I'm properly prepared.

Thanks in advance
