Eh sayang, ini soalan yang quite specific pasal adoption law, honestly lagi baik you contact the Social Welfare Department or a family lawyer yang tahu the actual legal process untuk anak angkat berstatus bukan warganegara, sebab regulations tu detail dan boleh beza depending on the child's origin country. A few of us dalam mom group ada anak angkat, tapi most of them went through proper agency or government channels, so better safe than sorry you get the exact official info!
