How to apply for an extension of a Tourist Visa?
A. An alien must apply for a Tourist Visa at a Thai Embassy or Consulate abroad prior to entering the Kingdom. Upon entering the country, as warranted by a tourist visa, permission will be granted for a stay of 60 days. Usually, if the alien wants to continue touring the country, an extension may be granted for not more than 30 days, unless there are exonerating circumstances, which would entitle the alien to a 1-year extension.
