I think there's a misunderstanding, take my case for example.
I do not live in Pattaya but use an agent there at Jomtien IO, the address on my paperwork is the agents office. If i want a COR i will pay the agent to get me COR but it's likely i'd need to go there and comply with more BS such as medical cert for COR.
For me going to Pattaya is no problemo as i have a property there.
