In accordance with the Immigration Act of 1979, Section 34 (10) any non-Thai individual gets hold of the approval to enter the Kingdom for temporary stay for educational purpose.
Under Section 35 (3) of the Act, those entering the Kingdom with an educational permit will not be allowed to stay here for a time period exceeding one year. It further states that under exceptional cases where the individual needs to stay for longer than the prescribed period, permission may be granted, but not more than one year at a time. When applying for an extension of temporary stay each time, he/she shall submit an application and pay the fees as required under the Ministerial Regulations.
There are two methods under which educational visa is granted to the students for studying in any institutes of Thailand :
Having obtained a student visa, which is valid for 90 days, you will need to file for an extension if you wish to stay in the Kingdom for a longer period. It is recommended that you contact the immigration department for an extension of stay no less than 15 days before the expiry date of your visa, in order for the officials to process your application. The fee for the extension of stay for a student visa is 1,900 THB for each time and is valid for one year, whereby the student will be required to make a notification of stay in the Kingdom every 90 days at any immigration office throughout the country.
