Does having an overstay affect your future entry into Thailand?

Having an overstay in Thailand does not automatically bar future entry, but the extent of the overstay and individual circumstances can influence the experience. Most users indicate that minor overstays (like a few days) have not deterred their ability to re-enter, although they acknowledged the requirement to pay fines. However, if the overstay is significant, it may lead to blacklisting for a period, ranging from one to ten years. It's vital to comply with immigration laws to avoid complications.
