How can I obtain a Non-O visa in Thailand without any connections?

To obtain a NON-O visa in Thailand without knowing anyone, you can apply directly if you're 50 years or older by meeting certain financial requirements (like having 800,000 THB in your bank account) and providing necessary documents including a bank letter and proof of address. Some commenters advised using visa agents for assistance, while others highlighted that speaking directly with immigration can also be effective. If you're under 50, options like the DTV visa were suggested, though the NON-O visa is primarily aimed at retirees or individuals with certain family connections.
