When does the 6-month tourist visa start: upon entry or issuance?

The 6-month Multiple Entry Tourist Visa (METV) is valid for 6 months starting from the date it is issued by the embassy, not the date of entry into Thailand. Travelers should apply for the visa considering this timeframe. Additionally, an outbound ticket is required, typically for a flight out within 60 days after entry. Some embassy requirements for the METV include proof of multiple entries, which may necessitate showing a flight itinerary in and out of Thailand.
