Ok, US citizen flying in on the 27th of April and leaving the 23rd of September. Appling online now for a multi entry visa. Plan on leaving Thailand a few times in between. On the application should I put April 27th to September the 23rd or show I'm leaving in sixty days. I have no problem buying a cheap one way ticket to Vietnam showing I'm leaving in sixty days. Also the site says they can choose to give me a single entry visa and no refund on the difference between the two prices. $40 for single and $200 for multiple. Thanks
