now you've completely lost me... must be some serious misunderstanding between us.. :
What does this mean : "diff between using agent (cheaper) and the 800k method" ?
There is no cheap agent method to get the retirement visa. Unless maybe some illegal under the table method you are referring to ?
OP wasn't talking about diff between 800k and agent. OP was talking about the cost of the 800K method, in which he thinks you have to pay an agent for something which most of the times is quicker to do yourself than to contact an agent. Why would you even pay for that ? Doesn't make any sense.
You'd pay for something when your time is too valuable, which in case of 90 days reporting in most cases isn't. But OP taking into consideration some ridiculous loose change costs, suggests tho me it could make a difference.
If OP makes so much money that paying an agent is worth it instead of reporting himself, then why even mention the cost of photocopies (2 baht per page ?) or bank letter (100 baht).
You throw money away to agents for something you can do yourself for free, but at the same time you're worried about the cost of bank letters and copies ? It takes more time to even only contact an agent than to do the 90 day reporting itself (when the online reporting is working)
Maybe then you also have to take into account your bus fare or taxi cost ?
And Elite Visa holders also have to do 90 day reporting. And if you stay longer than 12 months on Thailand, then Elite Visa holders also have to do an extension of stay.
1) As someone already said : you can apply from your phone.
But if you feel more comfortable doing it from your computer, then...
(2) ...an easy way to transfer pictures from your phone to computer for those not tech savvy is to mail the pictures it to yourself from your phone, and then open your mail on your computer and save it there for further use.
1) April is still a "long time" , nobody knows what the rules will be by then.
2) If I were in your case, I wouldn't risk to have gf come stay together on that 5th day. Because if you would test positive, she could be in trouble because she was in high risk close contact.
If you test positive and she doesn't stay with you that day, she can just do some ATK self testing and self isolate if necessary instead of risking being held hostage by the hotel/ hospital and paying too much for whatever forced quarantaine and unnecessary medicines.
