For Chonburi, to acquire an extension of stay, in some situations, they want a person to go to immigration for the last week of the "ADMITTED TO" stamp. For Chonburi, to acquire an in-country visa, they NEED AT LEAST 15 days remaining on the "ADMITTED TO" stamp. SOME immigration offices require at least 21 days.
You can contact them at
Chonburi Immigration Office Website:
