Just a thought... maybe consider the DTV? Since you are already posting in the group a quick search to see what category you qualify for might be a good start. You'll probably still need an agent to help set up the bank account though.
At the beginning of the e-visa there is a pop up that states that you acknowledge that you can't be in Thailand when you apply. There is also this little note under current location "Your current location is a country or territory in which you remain at the time that you lodge an application" that everyone seems to ignore.
as pointed out it's embassy dependent. If you haven't already join Destination Thailand Visa (DTV). Search in that group, there are loads of posts that will answer your questions. Once you decide which embassy to go to, the rest is fairly simple.
wouldn't recommend Malaysia, they are reported to be slow and want all sorts of additional documents. Hanoi is reported to be one of the quickest embassies for DTV's right now. If they don't ask for anything additional, they are 5 business days but you have to provide the entry stamp and paid hotel booking. Cambodia is 10-15.
you may have to prove that you still meet the requirements for the category you applied under. In this case that they still have permission/are working remote or in others still undergoing treatment or taking whatever course you applied with.
Every embassy is a little different with this requirement so you need to ask them. We are also joint account holders and had to show bank balance of 1M THB for my dependent spouse DTV at the Thai consulate in Vancouver..
The only thing the Thailand e-visa system does is change the method of sending in your information. It's still processed by the local Thai embassy or consulate based on where you are. The embassy can and has asked for proof you are in the country like passport pages and proof of fully paid hotel bookings. They can also ask people to come in for interviews. There is also this little note under current location "Your current location is a country or territory in which you remain at the time that you lodge an application" that everyone seems to ignore.
yeah, I hear you on that... an hour at immigration isn't horrible and we also have no issue with providing the required documents. I think for most people, thinking soft power, it will depend on the requirements regarding classes or ongoing medical treatment. If you travel a lot it's a non issue, but those that don't will have to decide based on their circumstances. Will be interesting to see how it goes.
currently there are no requirements when you re-enter from a border bounce. Doesn't mean they won't pull you aside or ask questions, but no one has reported being asking for "proof" doing a bounce.
