What are the options for extending a Non-B visa to a one-year visa in Thailand with a registered company and one employee?

The user is seeking clarification on extending their 3-month Non-B visa, as they are currently the Managing Director of a registered company with one Thai employee. They want to know if becoming the sole director would affect their chances of extending to a one-year visa that requires employing at least 4 Thai staff members, along with the associated costs. Responses suggest a standard cost for visa extension is 1,900 THB, contingent on fulfilling specific requirements such as income taxes, social security contributions, and salaries for Thai employees. There's a distinction between extending the visa domestically and applying for a multi-entry Non-B visa abroad, with stricter requirements if pursued through the Immigration Office.
