Should I switch to a marriage visa since my Non-B visa extensions will no longer be available?

The user has been extending their Non-B visa for 14 years but has been informed by their company that they can no longer do so and must start doing visa runs to Savannakhet every three months. They are married to a Thai citizen and are considering switching to a marriage visa. Comments suggest that since the user is already on an extension, they may apply for a 1-year extension based on their marriage, possibly without needing to leave Thailand. They should confirm with their local immigration office if this is possible. It’s also noted that some previous applicants have managed to secure a Non-O visa at Savannakhet independently, indicating some flexibility in the process.
