Starting March 20, 2016, foreigners who overstay in Thailand for more than 90 days will be banned from re-entering the country. Under the new measures, foreigners overstaying in Thailand who willingly surrender to the authorities will be treated differently from those who are arrested and prosecuted in the way that the length of the ban will be different.
In the case of voluntary surrender, those who overstay for more than 90 days will be banned from re-entering for 1 year. Overstay for more than 1 year, more than 3 years and more than 5 years will face a ban of 3 years, 5 years and 10 years respectively.
In the case of arrest and prosecution, foreigners who overstay less than 1 year will face a ban of 5 years and 10 years for overstaying more than 1 year.
Hotels, apartments, hostels or home-owners who rent their houses or rooms to foreigners will be asked to report the stay of foreigners to the nearest immigration office via the internet so that officials can keep track of their stay in the Kingdom.
