Carrying on from this thread:
Tried to go for a 30 day extension at Jomtien only 5 days prior to stamp expiry of my tourist visa. Yet again I was given a Yellow Ticket telling me to come back one (1) business day prior.
Someone mentioned on the above thread a few of their friends got 30 day extensions through agents, with 10 days left on their visa exempt entry. They didn't even have a tourist visa. If I were to take an educated guess, going through an agent to get an extension 10 days prior to stamp expiry, the agents are paying off someone at Jomtien to do this.
Seems like if you don't want to pay an agent, they are trying to make life as hard as possible and tell you to come back one (1) day before stamp expiry.
Moral of the story, still DO NOT waste your time attempting to get extensions more then one business day prior, unless you want to pay an agent.
