Hi I'm from Chiang Mai.
I would like to know about deposit money for Non-O Visa (Gurdian Visa).
My son is in K1 and his int'l school provided documents for his student visa and Non-O visa for me.
School said we dont need to go out of Thailand as we meet 21 days rules. and they said I must have B 500,000 in bank at least 3 months before I apply visa.
If anyone have recent experience in changing visa from tourist to Non-O here, when do you need to deposit B 500,000 to bank?

before apply the visa or before extend you visa?
Is it different if we go out of country and apply visa? (last six month ago my friend n his daughter went to laos and apply visas. He got Non-O 3 months and no need to show money. He needed to show money in bank for one month before extension)
I read several topics in forum and immigation rules too but still confuse and want to know their recent rules. Thank you

May

You will have to go to an embassy or consulate to get your non-o visa. Immigration will not do a conversion to a non immigrant visa based upon qualifying for an extension of stay based upon being the parent of a child attending school (it is not a guardian extension).

Unless you are in Bangkok your child will also have to go out for his non-ed visa. It would be best to get their non-ed visa and your non-o at the same time from an embassy or consulate.

To apply for the non-o visa you will not need to show the 500k batht in the bank. That will only be needed when you apply for the extension of stay.

Thank you ubonjoe.
I went to the CM immigration and wait 2 days to meet officer.
My son still have 24 working days left in his visa and he can change w/o going out but not me.
So I decide to go out both of us to change visa.
For B 500,000 she said I hv to deposit in bank at least one month before extension.

When I apply Non O visa, do I need my house owner's house book copy? I have lease agreement and her id copy with sign.

Thanks again.

You will not need the lease agreement to apply for the non-o visa.
