Oh ... So is RM30k the lowest credit card possible for Standard Chartered Platinum credit card ? Someone said the lowest credit card possible for UOB Bank Preferred Platinum credit card is much lower, around RM20k if my memory serves me correctly. As for HSBC VISA Platinum, the lowest credit line possible is RM30k. Was told its credit line cannot be any lower than RM30k, period ! If you are looking for a HSBC credit card with lower card, they will suggest you to apply for a Gold credit card instead.
How long have you been working ? Most banks require you to submit 2-3 months of payslip.

BE form is a form to be submitted to Income Revenue Board declaring your yearly income activities for calculation of income tax. Since you have just started working, you definitely don't have it now. Anyhow, it is advisable not to provide this document to bank for cc application, as it is a very personal information.

Most banks won't allow you to re-apply for cc within a short period after your application being rejected. I suggest you to patiently wait until you get your job confirmation.
