I had to cancel my PR appointment first time round because of a job change just before the appointment date. Got another appointment and this time I realize I don't have one of the required documents (birth cert).
This is stupid of me, but I wouldn't be able to get another birth cert in 2 days' time, which is when the appointment is

Is it okay if I submit my application *without* the birth cert? Or would ICA be okay if I submit it later (submit other documents first)? Alternatively, if I cancel this appointment (2nd time), does it mean I'll never ever be able for a PR again?

Much appreciate if someone could help me out please.
