This is obv Sandflies, not spiders. And yes, mosquitoes can cause blisters, etc. But no, u cannot contract Lyme disease in Thailand, it's not a thing here. I live in Thai countryside for many years with spiders, centipedes, snakes, scorpions, crabs, and every type of lizard and insect you can think of. I've had blisters similar to all the pictures above many times and it's always from insects/flies. No need for hospital, home remedies can do the job. In fact, here is a video of what the outside of my house looks like on certain nights.
If you are not legally married then you are way too early in the process. Get married first, even if you don't end up using it for the marriage extension because you choose another visa, it will be helpful in the future and you won't have to repeat this process ever again.
Are you legally married? If so you can since you had a Non-O before (you needed that for your volunteer visa). But again you are re-entering the eternal bribery loop which is something that im personally trying to get away from.
Im confused as tho what is included in the 70-100k+ price? I payed 1.2k for affidavit, 2.5k for translation+certification with agent (maybe even less), and $0 for marriage certificate at local district office. So overall 3.7k + round trip to Bangkok, 1 night hotel, and I am now legally married.
Nobody give a bleep about the Day 5 test. Nobody will arrest you for nor reporting. Worse that happened to people is a small fine upon departure for "forgetting" the Day 5 test. Thai rules are often subject to interpretation and each rule don't hold the same value. Following "every laws" to a tee is not something that any foreigner living here would ever recommend.
Your answer basically proves that you do not have a good grasp of the situation since you never once used an agent :). How are you qualify to answer agent questions if you have no idea what you are talking about?
Well, ofc, but with that absence of road rules in Thailand comes a much higher mortality rate. I'm with you, you get pulled over and instead of losing some points, you get fined 500 baht. For us foreigners, it's great to know we can get away with a lot if we have some $. I think that overall for superhighways, below 120km you won't get a ticket in Canada. They are tougher in residential and especially in school areas where the limit is often 30-40km. I agree with such restrictions to protect children. What they are doing in Japan, for example, in residential areas, is perfect to avoid accidents. As for your back road example, I totally agree with you. p.s: Canada has tough winter which destroys roads. Thai climate is very keen on keeping roads in pretty good conditions.
I can easily name 10+ things that Canada is horrible at. One of the major ones is the education system. Canadian schools are outdated and lagging behind other first-world countries, especially in Scandinavia.
