Why do I need to make a border run if my teaching visa and paperwork are in order?

Border runs in Thailand are often required due to the duration limitations of certain visas. Even if your teaching visa is valid and all paperwork is submitted, your visa may have a specific timeframe that necessitates a border run to reset your stay duration or to obtain a new visa or extension. This can be confusing, especially if your purpose in Thailand is already established, but it's a common requirement for many types of visas.
