News about my education (ED) visa

Today at my school I got informed, that I will not get tested by the Ministry of Education. The MoE stopped doing that. Instead there will only be a test at the school.

They also informed me, that I will have to leave the country and apply for a new visa after the 3rd or 4th extension of stay. The new visa would allow me to stay up to 6 months (I guess with extensions).

I got my Non-Immigrant ED (single-entry) visa on April 26th this year in Vientiane. I've extended my stay once and will do it tomorrow again. At school they said, that I would have to do the test in December and then around 3 weeks later I would have to go and apply for a new visa.

Just wanted to know, if anybody else heard of that or got that information.
