So, is it just premier and gold class or in all classes ?
Just 3 months will do actually.

It could be that your record is too clean or you've been a guarantor to someone else that someone else has defaulted on his bills before, thus affecting you.

Anyway, you can try some other more lenient banks such as CIMB Bank, Citibank or Standard Chartered Bank.

no la... normally after 3 months they will give... as long as ur background is clean...

maybe u can try some "aggressive bank" first... like CITIBANK, OCBC.

Your salary credited to which bank? If Maybank, get the branch manager to give you pre approved credit card easier.

Mind to tell which Uni you graduated from ? 

For first-timer CC applicants, just keep try applying all banks. You need the first card as your future reference. Most likely you may not get the bank of your choice.

Same with me, my first CC, prefer Citibank. But was rejected. So I applied MBB and got it.
