What type of visa I should apply for my wife and kids ?

Hi Forum. I am a Indian national with singapore PR with my wife and 3 kids with 8,6&4 years planning to move to johor bahru and continue their school in international school. I am planning to buy a property in Johor bahru. Currently my wife and my kids are living in Singapore holding Long term visit passes. Can anyone guide me what type of visa I should apply for my wife and kids.
Thank you

I think... the kids can apply student pass through the international school. Then, your wife can apply for guardian visa (guardian for the kids), also through the international school.
