There's no such thing as "adding someone" to your application.
You can apply for DTV, and then if you get it, you are eligible to sponsor for dependent visas based on yours. That would only be for children and spouse, if officially married.
You would first need to receive your DTV before the dependent applies for their own DTV and references your DTV that has already been issued.
It will be unlocked when they unlock it. Some people have reported by the end of the day they went into the office, others have said it's been more than a week. With thousands of people having to go in to provide this information, it's likely to take a while.
I haven't heard this, but it wouldn't be a surprise. Something similar happened during the last crackdown a few years ago when they also cancelled a bunch of ED visas and over 100 immigration officers were punished.
I would just try contacting a couple schools and ask them, they are the ones who are most likely to know as it would be affecting their customers.
If you're asking specifically for the re-entry permit application, it really doesn't matter what you put. Just make a guess, put a date, and then get your permit that you can use for the entirety of your extension. You don't need to book anything.
That's up to you. It can make getting through the border faster if you apply online a few days before. Otherwise you wait in line with everyone else for visa on arrival.
not necessary. Just want to make sure you don't submit the application then sit around waiting for nothing. Once you pay it should be less than a week until you have your visa.
Just make sure you realize that you have to submit your visa application online after entering Laos, but your application is not complete until you go to the embassy between 9-11AM and make the payment for the application in cash. Only Laos and Myanmar have this oddity about paying in person (and Myanmar even requires an appointment to pay.)
maybe you "rescue" a dog some Thai person considers theirs.
Maybe a local food vendor considers your handing out free food as stealing their business.
Maybe a Thai person that collects recyclables from the beach doesn't like your cleaning up as it eats into their income.
Everything has 2 sides. Just because you consider something only beneficial doesn't mean everyone will see it that way. And Thai people are the ones you have to worry about complaining as they are the ones the officials will take seriously.
