Each country is different Normally they go back 10 years or more..

Do you need to report if you have been expelled or removed from anther country. I know a guy who has anger issues and he was expelled for family violence. Bashed his Ex. She took out an AVO and he was convicted for breaching it. Don't think he reported it. Most countries require this disclosure when applying for a visa. Should show on a Plaice check but the country was not his permanent place of residence.

And do you have to report expulsion or exclusion from other countries?

There is also this site,

Its the official Thai government web site.

Thai Immigration web site.

Read the official rules on the Thai immigration web site. I avoided the owner needing to pay a fine by staying in hotel one night. Immigration was clear it is not my responsibility buy the owner. The owner is responsible, If you have a visa that is more than 90days then yes there is a different rule that requires the visa holder to register. They just check the data base to see if your name is there. New toys. All movements in and out of the country are logged on the database. I was shown the data record.

you have to be registered within 24 hours of your arrival. It really only needs to be done once per visa or 90 days

Buy the time you pay the 1900 plus the 1600thb it is cheaper for your to cross the border. But time consuming. It is a scam in my book
