An Iraqi man has been arrested in Kanchanaburi for overstaying his visa by almost 15 years.
Immigration police arrested Oday Jabbar Khudhair, 43, at a guesthouse on Thursday.
The arrest followed a complaint that a foreigner had been acting suspiciously and might have committed an immigration offence, authorities said. He had reportedly moved from another part of the country to stay in Kanchanaburi.
Immigration police went to the guesthouse where they found Mr Khudhair. His passport showed his visa had expired on Aug 21, 2008.
Mr Khudhair was charged with overstaying his visa by 5,468 days and detained.
The fine for overstaying a visa is 500 baht per day but the maximum is 20,000 baht.
For more serious cases, an overstayer will be deported and banned from re-entering Thailand for a certain period. Those overstaying for more than 5 years will be banned from entering the country for 10 years.
