What visa options are available for bringing my child to Thailand as a spouse of a Thai citizen?

LF recommendations / suggestions:

I am married to a Thai citizen. I have a 7 year old daughter from previous failed relationship who is currently residing in the PH.

Currently I am in Thailand under Non-Immigrant O visa and planning to go back to Philippine and bring my kid to Thailand for good.

Can you suggest to me what visa should I use aside from the Student visa? (the student visa was recommended by the Royal Thai Embassy)

>> I have a problem with student visa. I cannot get the requirements from the Sarasas school because the pre-requirement is that my kid should be able to write and read in Thai language. Therefore, I want to bring her first to Thailand and learn everything once she arrives here and enroll her to school once she is capable to read and write in Thai.

If I find a job before I go back to PH and get a working visa, would that help and can I apply for my kid the non-immigrant dependent O visa?

Anyone? Please enlighten me. I feel frustrated. Thus, inter-country adoptation will take 4 years of processing also 😭 based from google.
