Those who come from India, China, African, Middle Eastern countries and some African countries need to return to their home country to receive a non-immigrant “ED” visa from their local Thai Embassy or consulate.
All African and Middle Eastern nationalities also need to obtain a criminal record check letter from either their country of origin or from the Royal Thai Police in order to apply for a non-immigrant “ED” visa. Please start the process of application with Pro Language 3 to 4 weeks BEFORE your current visa is due to expire.
