What are the long-term extension options for a 90-day Non-O visa in Thailand and the financial requirements?

The user has a 90-day Non-O visa based on a birth certificate and is inquiring about options for a long-term extension. The primary responses indicate that the user can extend the visa for 60 days and also has the option to apply for a year extension if they have legal parental rights over a half-Thai child. This requires navigating family court if the child was born out of wedlock. The financial requirements for this extension include having 400,000 THB in a Thai bank account or proof of 12 consecutive months of transferring at least 40,000 THB from abroad. An alternative is the Thai ELITE Visa, which costs 500,000 THB for a 5-year stay.
