The EDB treats foreign and local homeschool families mostly the same. The procedure usually goes as follows: After you notify the EDB that you are homeschooling or intend to homeschool, they may try to persuade you to send your child to school, which they think it is a better way.
The EDB officers will request your information--your name, occupation, contact, reasons of homeschooling, curriculum, evaluation methods, etc. Then they may request to meet you (and maybe your child) in their office.
The government views a high quality education as the right of every child living in Hong Kong. After discussing your homeschooling methods, if they do not have a major concern, they will not approve or disapprove your homeschooling, but say they would like to do a home visit around 2 times per year. This lack of non-approval is essentially permission for you to homeschool. If, however, they found major concerns with your situation, they could issue an attendance order which would legally require you to send your child to school. But the EDB very rarely issues attendance orders. We are only aware of 3 cases since the year 2000 when the EDB has issued an attendance order to a homeschooling family.
