The people in the consulate won’t know you live next door. They also won’t care. If you’ve got the paperwork they want to see they’ll give you the visa.
You’ll be staying right on the border with Laos in Chiang Kong. Makes sense to do it right there. There’s no reason to leave a border town and schlep all the way to the airport to fly out and back when you can just get it done where you are.
Another thing worth considering is that if you, for whatever reason, lose your job, you no longer have a valid extension of stay. If you get a work permit on an extension based on marriage, and you stop working, you still have your permission of stay.
Your permission to stay, and your visa, are now things of the past. You will need to start again. If you arrive in Thailand without a visa you will get the 30 day visa exempt entry.
As mentioned above, and in this group many times before, re entry permits should be bought before you leave in order to keep your permission to stay valid. If that’s not done your current permission to stay ends when you leave.
That depends on which country you are entering. Some Cambodian border posts want you to stay 24 hours before you leave again. Laos and Myanmar don’t. In fact, some places in Myanmar only give you a day pass so you have to leave the same day.
If you told the guy in Penang you had a visa, he was correct. The fact that you don’t, you have an extension of stay, means you need to cancel it before you leave.
it says that if you use the London embassy you won’t find out if your application is successful or not until you get your passport back. As opposed to using their service where they tell you if you’ll get the visa you asked for or not after you’ve sent them the documents, and before you go there.
