Went to CM immigration today (Friday afternoon) for family extension.
Arrived a bit early at 12:45pm as I didn't have any of the application forms (extension form, warning form, acknowledge form, map form, all x2). Filled out the forms by 1pm when they opened after lunch, out with stamped passport (under consideration) by 2pm. Nobody in front of me at any stage, biggest wait was between them accepting the forms and taking my photo (about 10-15 mins).
Lady said they only had 1 family application this morning, and mine was the second for the day.
Your post confused me!
