hi all, i’ll be applying for soft power dtv visa in hanoi. those who have gone this route, what documents were required of you and do you reccomend me using an agent to do this or just doing it myself? also how long did it take from submitting application to being approved to enter?

Hello everyone. I was wondering if anyone has recent experience getting a 90 day non-immigrant O visa with intent to get a one year retirement visa in Bangkok doing it themselves. I have heard so much conflicting info regarding what is posted on the Thai Immigration website versus what may be asked for when I apply in person so debating just sticking with an agent. Any thoughts oh great hive mind?
