Malaysian Passport Renewal in Singapore

Where: Malaysian High Commission @ 301 Jervois Road
When: 8am -1130am (Submission) || 2:30pm - 4:15pm (Collection)
How: Read caibin's comment at worm's perspective (Thanks Kap Lam for finding me this info before we went. :) )
Efficiency: High, one day

We went at Tuesday by taking the earliest 199 bus, reached there around late 7. I got the pass number of I-15, finished the application by 9am, came back to take at late 2, got it at 3 plus. So few additional hints are:

1. The electronic form of IM.42 can be obtained at this site.

2. Go there early, with 3 serving counters and efficiency of 5 minutes per application, the high commission can process about 100 application per day. That's the reason why the pass in guard house is limited.

3. Bring along PR/employment pass/student pass. We didn't know this but luckily we always bring along with us.

4. There's a photo taking and photocopy machine.

5. After submission, you can collect at another day.

Officers there are very friendly, one officer even started the conversation with me.

Officer: Emak kamu Chinese? (Are your mother Chinese?)
Me: Ya.
Officer: Bapa juga? (Your father also?)
Me: Ya.
Officer: Jadi mengapa rambut kamu kerinting? (Then why your hair is curly?)
... @.@ +.+ -_-
（FYI, curly hair is the dominant gene)

I finally understood why my US visa application needs longer time to process.
