What Other Documents Do You Need for an Education Visa Application in Laos?

For those who have recently done an Education Visa in Laos, Vientiane were any other documents needed other than Visa Application along with School Paperwork Provided by the School your are attending?

Bank Statements, Proof Of Residency, etc anything like this needed? My research on Laos Thai Embassy Site does not say any of these documents required for ED Visa.. What are other experiences recently?

Much Appreciated 📷
