I am Canadian citizen, normally live in Myanmar but for now, I am living in Chiang Mai, until things get sorted over there. I am thinking to travel from Chiang Mai to Laos soon to obtain a 90 days Non O visa based on retirement and one for my Burmese wife as accompanying spouse. I currently have a STV visa and multiple Covid extensions. 800 000 THB has been in the Bangkok bank for several months already. I also have a TM30 for the house I rent in Chiang Mai. What are other required documents I must show?

I need to know if USD$100 000 insurance is required for the Non O visa when applying in Laos. For each of us ?

Is the Non O actually the visa I need to get the 1 year extension later in Chiang Mai ? Is there an advantage in getting the Non O as opposed to entering the Kingdom on a regular tourist visa

Between Vientiane and Savannakhet, not sure which is the friendliest Thai visa office (least burdensome). Advise please.

I actually direct my questions to the page moderators as they know their stuff very well. People who have done similar can also leave a comment please.
