Hello,

If your system language is set to English and some programs are in a different language, you'll probably have to set the language individually for each of those programs, or download/install an English version of those programs. Here are instructions on how to change the language in iTunes to English.

Well said.

A lot of website do a reverse look up of your IP. If your IP locates you in Thailand then you can get pages offered in that language. There is usually a button to switch the language of the page that you can use if you visit such a site regularly. This choice is stored in a cookie that you need to keep via an allow exception. Otherwise you would have to use a VPN service that locates you in the US or another English speaking country.

You can use websites like these to see how your location is reported via a reverse DNS look up of your IP:
