No difference. Different requirements nonetheless. Actually I was mainly referring to eVisa. There are only a few traditional consulates with paper sticker visa and personal appointment left. Mainly in Thailands neighboring countries. There they would issue the DTV (IF they do at all for non-residents!) on the spot or within just a few days. However, requirements also differ significantly amongst them.
Definitely check with the Thai consulate in your jurisdiction. From various reports, requirements for that path vary drastically from consulate to consulate in terms of how long e.g. the course needs to be and other requirements (TiT).
Hm. I don't know about all consulates, but at least here in Germany, they will only allow applications up to 3 months in advance. Also, there is no more proof of flight tickets required / no upload - just mentioning a flight in form.
Many consulates only accept applications up to 3 months in advance. And why would you apply earlier than that? The DTV is valid and its 5 year clock running from the day it is issued. Most consulates also publish how many working days they require for issuing visa. In general I would say: Do it between 15 and 30 (working) days before your intended travel date when applying through eVisa. And no, in the eVisa system at least there is no more proof of flight ticket required.
Yes. So far the UK embassy was the fastest and most pain-free. They don’t seem to care to wait for clarity. They just sell DTV visa as quickly as they can.
