Hansel, prince_mk ,managed to open my DBS MCA at Marina Bay     
Thank you sifu 

Considering I am currently unemployed, it's a miracle they let me open. 

Here's how I manage to open. Requirement by DBS to open account with them
No 3 was problematic. I decided to go the way of opening a Philips account first. Once I opened that, I had a copy of application proof which I can give to the bank. They were problematic as well and refuse to open without a Singapore bank account. But somehow they told me we will open for you and hang on to your application unless you can provide us the Singapore bank account no. They did give me a proof of application. This was done at Toa Payoh branch.

Headed over to Marina Bay. Told them want to open Vickers and MCA. Apparently one cannot open Vickers without a bank account. So had to deal with MCA first.

Note:
Now MCA have foreign charges regardless when you open starting next monday. All MCA have free first 5 years annual fee waiver. Then after the 5 years, you are required to pay SGD12 for another 5 years = SGD2.40/year.

It cannot be done in Malaysia. You need to send back to SG bank or visit the bank in SG for direct exchange.
