CMU is a university that's the difference from. Example a Language School.
And you mention you know there is a limit but it's something you heard from and person but you are not sure please how can that be more correct information. That makes no sense saying like that
Many just chose to change to a non o/a visa when they become 50 because that is the minimum age for what many would call a retirement visa after it's more easy even they still like to maybe study Thai.
If there was a max limited be sure all schools would ah e itt mention in their websites.
So no source other then haven't heard about and the logic part whee schools would mention it hope that make sense to you
Yes Checked out the website but it was just for a single entry so I figured maybe they wanted some extra paperwork for the 1 year and as you also mention it redirected me to the KL embassy requirements that's why I asked the question as we all know rather a paper to much then one to little
