Can I extend my e-visa in Thailand more than once or do I need to do a border run after my first extension?

A 60-day e-visa can be extended once for an additional 30 days at an immigration office in Thailand. After this extension, you're required to leave the country unless you qualify for alternative extensions related to family ties (like having a Thai spouse or child). For further stays beyond the initial 90 days, border runs or visa exemptions may be necessary.
