Hi. I need to extend my daughter's non-o visa to be in line with mine. I have a non-b. What are the documents that are needed at CW immigration? I have her birth certificate verified as well as a Thai copy. A copy of my visa. The request for extension form. Is there anything else that is needed? We are South Africans so is there anything specific for us? I have tried looking for the information on the immigration website but have not been successful. Any help is appreciated. Thanks in advance.
