How can we check MM2H DEPENDANT PASS from online ?

Www.mm2h.gov.my

But only the Principle applicant needs approving so DP won't show in the online checker

Thank you for your information, Malaysia my second home dependent pass visa holder do they get i-KAD ? if issue i-KAD how can we get that from immigration ? please let me know. Thank you.

No Ikad for those on MM2H is issued at the moment (it was stopped about 7 years ago). It may be different if you have the Ikad based on a much earlier approval (i.e. you are adding a spouse to your own MM2H visa).

MM2H Approvals are currently suspended (since about August 2018) so don't expect a decision any time soon. Apparently there are at least 3,000 applications stuck in a queue (Borneo Post)
