In order to clarify some doubts on the first part of the post I will make a (partially serious) digression into the different types of Thai ED (education) visas.
My visa, having being issued by a Thai Embassy at a bordering country - in my case it was Laos - is of the single entry type and even though it's valid for one year the period of stay must be extended every three months at the immigration office.
Furthermore, in case the single entry ED visa holder needs to leave the country a re-entry permit must be obtained first, in order to keep the visa "alive" while abroad.
If I had applied for the visa in Europe I would have been able to get a multiple entry one and there would have been no need to go to the immigration office every three months for an extension.
Even this type of visa presents some inconveniences though, as the holder will have to leave the country not less than once every ninety days, without applying for a re-entry permit though, in this case. Do you think it makes no sense? Don't worry, it probably doesn't, unless you manage to get into the details of the logic of a South-East Asian country's bureaucracy.
By the way, there are some additional complications. Let's assume that your current extension will expire on the 31st of the current month. As we have already said you need to show up at the immigration office before that day to get an extension of stay for ninety more days. You follow the advice of the Immigration Department and of your school and you report a few days in advance, let's say on the 25th. The extension will obviously start from the expiration day, which is the 31st, but unfortunately there is an annoying catch. Every three months it is also necessary to report for address notification. Fortunately these two things (extension of stay and notification of address) can be done on the same day, in our case on the 25th. As already said your stay will be extended for ninety days starting from the expiration day, which is the 31st, but the clock for your next address notification will start to run on the 25th! In brief, before your one-year visa expires you will have to go to the immigration office an extra time just to notify your address for the last time. It might seem useless to you, but only to you. Judging by the pieces of paper that they stuck to your passport, by the use of CAPITAL LETTERS, bold font and a considerable number of exclamation marks!!!, for them it must be a very crucial point.
Anyway a student visa is still better than a tourist one, as its holder is spared from having to embark every two months on one of those jolly journey generally known with the name of visa-runs.
