Along with the three things Tod mentioned, if you vacation in Vietnam, or somewhere else for a few weeks, that might slightly increase your chances, and make you look like a tourist.

@Arne *******

First, if you want to get 9 months out of your visa, you need to enter as soon as you get it. Do the calculations yourself:

- METV is valid for 6 months, need to enter and re-enter within those 6 months

- 60 days per entry with possibility to extend another 30 days

I'd say you probably won't be able to get 9 months out of your METV (you would be able to get two visa-exemption stamps per calendar year by land, though).

Second, if your girlfriend still hasn't gotten her visa, the time used up to get her visa is eating away at the time of your METV.

Third, if your girlfriend gets her visa a few weeks after yours, the timing of your border runs will be different. You will have to do your border runs separately, or one of you will have to lose a few weeks from the total time of their visa.

Fourth, another option is to get a SETV, which gives you 60 days, and the possibility to extend for another 30 days for 1,900฿ at immigration. You can wait before entering, because there are no re-entries. Then, you are allowed 2 visa-exemption stamps per calendar year by land, which since October 1st gives you 45 days, and the possibility to extend for another 30 days.

I've given you all the information you need, to do the math according to your travel plans.

For a good understanding of the METV, see Tod's explanation in this post:

Read and re-read Tod's answer. That's how a METV works. To get the most out of the METV (almost a full 9 months), you have to enter the country as soon as you get the visa.

If you don't enter right away, you're wasting away your METV. Might as well have gotten a SETV and used two visa exempts stamps instead (8 months total).

@Stuart *******

That's why you get a cheap $50 Air Asia online, within the 54 days even (since the airline might not know about the 45-day change, or even about extensions), and you show them that ticket, and not your other return ticket. You can use that cheap ticket, or not use it at all.

@Stuart *******

Had you entered everything correctly, you would have probably been rejected for the overstay. An embassy will not approve a visa for someone planning on overstaying.

@Jamie **********

You're recommending this, but have you ever used one of these? And how recently?

Just buy a $50 Air Asia ticket to a neighbouring country. Paying $50 instead of $15 for a sketchy service, and not risk losing your expensive flight and trip.

@Stuart *******

Don't change your expensive ticket. Just buy a cheap Air Asia ticket for $50 to a neighbouring country, and show that. Use it or don't use it. I wouldn't risk losing your flight by using one of those onward ticket sites.

@Stuart *******

It's probably one of the reasons why your visa was rejected. Embassies don't approve of people PLANNING on overstaying.

@Graham ******

How did you apply for a Non-Immigrant B e-visa from Canada? You had all the many required documents from your job, and you provided these to them electronically? I know it's possible to provide physical documents at embassy in Canada, but not electronic documents for a "Non-Immigrant B evisa."
