I have been living here in Thailand on a Business (B) Visa extension and Work permit for several years with my Thai wife to whom I am legally married here in Thailand. We are residing in Nonthaburi province.
We have just got a child and we would like my mother to spend some time with us, half a year up to one year, to help us in taking care of our child.
My mother is currently staying with us here in Nonthaburi province holding an O Type VISA with Single entry that is valid for only 3 months.
Can anyone please advise if it is possible for her to extend her O Type single entry VISA from 3 months to a year, and what would be requirements / necessary documents for her to do so?
Thank you in advance!
