Regarding the provision (clause 2.28) in the current Immigration Order 327/2557 concerning the extension of stays that allows immigration to give 30-day extension “based on embassy request”:
Has anyone tried to get one of these letters from Embassy of USA?
Also, a story posted on a non-government website says "some immigration offices may issue the extension without the embassy letter as long as you are able to show proof of cancellation of your flight." Has anyone tried this? Which office and what happened?
