Very easy, most others I've seen got it within 5-7 working days and it's all online (except if you don't have CIMB Malaysia or if your CIMB Malaysia was dormant like me...)
I was one of the few unlucky batch whom applied during CIMB MY/SG new hiring and they screwed up with my application procedure (rejecting my linkage )

For opening sg account you can read more in this thread or this step by step guide I compiled

The initial linkage is to grant you access to view Singapore account, from Malaysia's CIMB Clicks. This allows you to do internal transfers without FOREX fees (though exchange rate are still marked up). Your Malaysia account is still there as the primary one, Singapore account is for your visibility only. You cannot do Singapore transactions via Malaysia clicks.

At this point your Singapore account hasn't been approved yet - as they'll be waiting for your internal transfer (at least 1 SGD) for E-KYC verification process.

Once you completed ekyc and have 1k SGD, your Singapore account will be reviewed, and typically approved within 2-3 days. Once approved, you will receive SMS containing login details to CIMB CLICKS Singapore. In cimb clicks sg, you can only perform Singapore transactions (FAST transfer etc.)

no, it is just the display delay, u still trade on real time price.

so make sure you place your order by referring to external real-time price, not the price shown.

You need to fund it. It's part of their verification process.
Not sure how much. Last time I fund USD 5k

I see okay.

Is it sufficient enough to just hold VWRA?

Or do I need to diversify and hold another ETFs too. If so which?

Thanks and appreciate the help.
