your chance will be higher if you got CCRIS good record, basically you need 6months+ of good payment record on ur OCBC card.. but again, the UOB card approval depends on bank evaluation

ANY UOB Credit Card agent plz PM me.

U can actually send all your supporting documents to uobcustomerservice@uob.com.my directly instead of waiting them to call u.
I did the same, and i got reply the next day saying that they forwarded my email with all the documents to credit card department.

i believed they do follow the PDPA Rule.
However, for identity Card its better to put a remark like "For UOB only" into it to avoid misuse like what u said.
