Will a Non-O visa application be rejected if income is from wages instead of pension?

With a non-O visa/extension the restriction on employment is only within Thailand. Many non-O holders are FIFO workers who are in and out of Thailand on a regular basis. This practice is fine, and the monthly transfers of 65k can be from overseas employment. Although I'm not a FIFO worker, my first three years in Thailand, I was still working in my law firm for six months of the year. I had no pension at that stage, but Bangkok Immigration do not ask to see where the money from overseas comes from. I also moved around Thailand a bit for several years and other immigration offices I used similarly simply accepted the monthly transfers. The only criteria is the money MUST be transferred from overseas

Just put 400k in a thai account and be done with it. Its so easy, and if you can't afford it then stay home and keep working until you can.

I’ll ask a friend, who may be able to help your friend. That’s what friends are for 😂🤣

You said you are married same here. 2 years I have retired and getting a small private pension.

I have got the O visa for 90 days. In which time I will open a bank account with ten thousand pounds off four hundred thousand thai bahts to get the married year visa leaving this money in the bank guarantees that I will always have the right amount of money plus if the government gets tighter with regulations.And I have to leave, i've got some starting up money back in the uk.Or wherever I would end up lol i am told by the site as soon as I arrive there next week if to go and get the bank account sorted. My wife has the house farm with her book already

Why not get marriage visa

We all have a 'friend' like that one

The source of the funds shouldn't matter for most embassies. Though he'll need to figure out how to get the extension in Thailand if that's the plan, because he won't be able to use monthly income there.
