Probably. Are there even more than a handful of Malaysians studying in NUS or SMU in the first place? I think there was a grand total of 1 or 2 Malaysians in my NUS batch years ago.

This is a very niche question which probably applies to less than 10 people per year across all 3 local law schools, so you're better off reaching out to your Malaysian peers directly. Furthermore, its hard to say how the market will respond to such a new development.

For obvious reasons and as a matter of policy, entry to the Bar is normally restricted to Singaporeans and PRs. Which is why overseas scheduled law grads must be citizens or SPRs to be "qualified persons".

Your easiest bet is to actually qualify in Malaysia and apply to work here as a foreign lawyer.
