It's possible but it's extremely tedious, I would highly suggest using an agent, if you don't want to use an agent you will spend days looking for a branch that will accept as each branch is governed by its own rules and with recent changes it's much harder. If you use an agent it will cost between 6-10k depending on where you are and save you a lot of time and hassle.
Depends on where she gets her visa, in Bangkok It isn't "full-time" or "part-time" anymore it's based on visa length. 3-6 month study time is a minimum of 2 days a week 3 hours per day. 6-12 month visa is 5 days per week 3 hours per day.
They are coming down hard on ED visas because of the continued abuse. Immigration does random visits to the school and I've even heard of cases where they have turned up several times in one week.
yeah, this is a new one on me too... I'm willing to bet it has something to do with farangs finally being held accountable for their atrocious behaviour when certain ones finally show their true colours. I've seen a few arsehats state it's "unfair" and "borderline discriminatory" 🙄
