Why did the Thai Government tighten visa exemption privileges?
The government has tightened the visa exemption privilege to prevent abuse. Abuse of the privilege include the so-called visa runs which some foreigners have been using to extend their stay by taking a bus to the border, checking out of the country and then returning the same day to have their visa exemption renewed. They used to repeat the practice as many times as they wanted, affording them almost unlimited stays in Thailand which was not acceptable for the government.
