Well, you have tried over and over didn't you? It's not like you didn't care about it. I made screenshots of conversations with mine where I repeatedly asked for it over the course of 2 months...
I had the same problem in Phuket and I got a thai colleague to call and make them get it done. I would refuse the fine and give the landlord's phone number and address to immigration to settle it. The extension wasn't a problem at the time but perhaps your officer will be less forgiving....
That is the thing Garrett. If you choose a degree in let's say architecture or business, stopping midway will mostly affect yourself. Perhaps the company working for, will struggle a bit finding someone else. But you are always replaceable. Teachers however, massively affect children by disappearing. I work at an International school and see it all the time. Children are left behind, find it difficult to build up a bond with their new teachers over and over again, kids with learning disabilities have to start all over again, etc. It's a negative outcome for the children and that is why I generally dislike it when someone's motivation to teach comes from an egocentric point of view. Of course OP can fall in love with teaching and happily do it for years to come. I truly hope that is the case.
I truly hope she finds it amazing and will put her future students' needs above all, but I've met plenty of people who did a TEFL just to be able to live abroad. It rarely benefits the kids as most of those teachers are making minimum effort and disappear after a couple of months to start somewhere else. Perhaps OP will make a difference :-)
I don't want to be negative Nancy here, but as a devoted teacher it annoys me a bit that you are considering teaching just to have a legal way of working in Thailand. That means you most probably will not be motivated 100% to be a positive and dedicated role model for your future students. In my opinion, teachers should be teaching if it is their passion, if they truly want to change children's future for the better. Perhaps there are other ways for you to work in Thailand? Have you considered the tourism industry?
I found out that you don't need to pay either. Getting a temporary license will only cost you money to post the paperwork to BKK. This temporary license will last you two years and can be extended another two times! Problem solved. If anyone needs more information as I'm researching this, PM me.
