Thanks everyone for the replies. It's looking more like the Penang option for me, but before commenting is closed I still hope to get confirmation from Amornrat. If there is a chance I can still obtain my SETV in Savannakhet, I would want to try. I really have very little history in Thailand. It's just recent. One flight in, one border run. But with extensions it gives me over 90 days in the past 6 months.

James Miller thank you. I just wanted to confirm here that the requirement is true, as I haven't seen it elsewhere. (I have only flown into Thailand once and did only one border crossing, but with two extensions it totals 4 months in the past 6)

The proof of funds OR onward ticket is still confusing though, as I've read here many times that you must have both.

Amornrat Mattioli that sounds wonderful but my co-worker is adamant that you can't do this, must already have Myanmar visa and proof that you have a Thai visa, etc. He has seen many people turned back at this border over 11 years. But then I hear other accounts and info such as yours.

@Ellie ******

yes I already got a 30 day extension at a local immigration office and it expires the day after tomorrow. I just need to leave Thailand and re-enter and I'm pressed for time, hence considering the nearby Mae Sot/Myawaddy border, but I"m getting very little information about doing such runs at this border crossing. Spent a lot of time googling and it seems people have done this border visa run before but it was a while ago and my co-worker seems adamant that it cannot be done. Must already have a Myanmar visa or some other conditions, yet I've seen online some accounts of easily getting a day pass into Myanmar for 500 baht to do this. Very confusing.

@James *******

thank you.
