Can I leave Thailand for a few days to Laos and then return to extend my non-O visa, or do I need to fly out of Thailand?

The inquiry revolves around extending a 90-day non-O visa for a married expat. The user, who is 67 and married to a Thai national, is considering a short trip to Laos to facilitate a 60-day extension upon re-entry, or alternatively, to fly out of Thailand for a similar effect. Community feedback indicates that a visit to the immigration office could grant a 60-day extension for those married to Thai citizens, along with a reminder to obtain a multiple re-entry permit if planning to leave Thailand during the visa extension period. Furthermore, it's emphasized that while land or air travel are both options, it is advisable to check specific immigration policies to avoid complications.
