It's not easy moving from one country to another. It is even harder when you have kids who are schooling. You will have to go through the rigors of finding or selecting a suitable international school for your kid(s). Also, your kid(s) will need some time to adjust to having new kids with an unfamiliar culture around them, not forgetting making friends with these kids.
By international school, we mean a school where your child can continue their learning process when you move to Thailand without any disruption of their familiar curriculum.
