First entry on 20th Jun after getting my DTV approved on 17th May. It took me literally 2 min to go thru inmigration in Bangkok. Showed my DTV (printed copy), alongside passport and TDAC to thw officer. No questions asked. Allowed to stay until 11th dec. Will leave earlier than that for business reasons, but it feels so good not to worry about length of my stay for the first time ever.
