What are the options for dealing with entry denial or blacklisting in Thailand, and do I need an immigration lawyer?

There's got to be more to this than a tourist being denied entry.

If he was blacklisted, why would he try to come back when he should know they will not let him in.

There are three things that come into play.

-Denied entry <- that's when you fly in but are NOT stamped into the country and instead held and either sent to any country you can get into or back to the country your passport comes from.

-Deported <- that is when you are already INSIDE the country, run amuck and are "invited to leave". It doesn't mean you're blacklisted or banned at all. It means what ever happened was serious enough for them to ship you out of the country BUT you can turn around and come right back in if you want to.

-Black-listing or Banning <- that is when you are prohibited from re-entering the country for a defined period of time. Before the overstay penalties concerning blacklisting came into effect most people who were black listed for 99 years (lifetime). Now there are 1, 3, 5 and 10 year blacklisting due to overstay.

New rules today!! 😔

What happened

Better with an agent certainly not a lawyer
