the first option requires less time abroad but unlike with other visas, the requirements for in-country switching to non-B are a little heavier than abroad, so various companies kindly ask prospective employees to stay abroad for some time.
So, if it's a respectable employer, it gets you a free trip to a neighboring country 😊
your prospective employer sounds serious and knowledgeable about the matter. I trust they'll guide you through the process. As any respectable employer would, by the way.
In principle, yes. The 500k baht equivalent is in generic requirements, meaning that it applies to you both. However, some embassies are a little more lenient and do not require the money for dependents. It is worth checking.
And even if the money is required for you both, you could still get around it by using the same 500k twice. That then depends on the seasoning requirement, which also differs per embassy. Some do not require any seasoning, so you could just send the money to your spouse to support his/her application. You can't apply simultaneously anyways if your spouse applies as your dependent; it must then be done sequentially.
and at the same time, the entire world keeps speaking of "visa extension", understanding that this also applies to exemption, and in these provinces people can't find their way to it anymore. No, I don't think that was a good call.
you can blame immigrations many things, but not this. Maybe the mistake is to call the visa exemption that, instead of the perhaps more suitable "visa on arrival". The problem is then that that term is already in use. But many more people would understand what is meant if you call it that. Then the term "visa extension" would be slightly more accurate. But even if it's not accurate, I think it's preferred they use this term over some other because everyone would just immediately understand what is meant. Internationally the term is used frequently, whereas if you'd speak of "extension of stay permit", many would think of permanent stayers and the like.
