and that's where the mind boggles: They use incorrect wording. They actually mean: if your stay permit is valid for less than one year, you can only get a 2-year renewal . . .It is the typical WRONG technical wording, DLT and Immigration are mixing up "visa" and "stay permit". These two authorities call a stay permit "a visa" and this is wrong. You ENTER Thailand on a visa, and then you are inside Thailand on a stay permit. If you go further, it means that all stay permits that got issued on a visa-exempt entry, on a tourist visa, on a METV, on a 90 days Non-Imm visa, and on a DTV, do NOT make you elegible for a 5-year renewal, because these stay permits are only for 60, 90 and 180 days - less than one year. I think what they meant to saywas - Only if you already got issued an Extension of the Stay Permit of exactly one year, you can apply for the 5-year renewal
