Can I apply for Thai permanent residency under the family category with a marriage visa and no work permit?

The user, Xavier, is a French national married to a Thai citizen, seeking advice on applying for Thai permanent residency under the family category. He has held a marriage visa since 2013 but has not worked in Thailand or paid income taxes. Comments suggest that a key requirement for residency involves having worked and paid taxes in Thailand for a minimum of three years, along with a basic fluency in the Thai language. Users recommend seeking information online and express concerns about Xavier's tax situation, while others suggest considering legal assistance for the application process.
