no , the paperwork is done in 5 minutes... They just don't want to and take the chance to sell you something useless. Ask what the commission is on that sale....
no , when I got non is in 2018 there where no request for insurance. And the first change was for 400k insurance, second 3m and now they are back to 400k.
it was really easy and then they added insurance. To renew there were only twelve Thai companies on the list with really bad and expensive insurance. So you neded an extra international anyway....
not likely since it is a 5 year visa. They might stop issuing them. So that means 5 years ahead of time. You don't have that on the rest. Just look at what happened to non OA.
