I entered on a non-immigrant single entry. I got a multi-entry stamp in my passport for 3800 Baht at the local immigration office in Ubon Ratchathani. I could also get a reentry for 1900 Baht.
@Peter Hedley. To give a correct answer, I need to know your nationality and whether you are asking about visa on arrival or visa-free stay. There are 93 countries that have a 60-day visa-free stay.
Are you required to notify immigration within 24 hours if you have been registered in another province and return to your place of residence before you have to report for 90 days?
This also applies if you have been away for a day to a neighboring country?.
If you are staying in Thailand for more than 3 months, the Thai authorities require you to have a Thai driver's license, even if you have an IDP that is valid for one year. A foreign driver's license can be converted to a Thai driver's license at DLT. This requires a minimum of 3 months visa, a residence certificate from Immigration and a medical certificate from a medical clinic, as well as a national and international driver's license.
