I offer the following reasons to reinforce my recommendation.


1) Currently, enrollment of foreign students into mainstream schools is capped at a proportion of 5%. Although not insignificant, when measured relative to the proportion of foreigners constituting the workforce in Singapore, this number definitely has room to go up to say 10%.


2) We do possess sufficient capacity in our primary schools to accept them as our local student population shrinks (read: more and more schools are either closing down or merging).


3) At merely 7 or 8 years of age , the minds of these foreign students are still very malleable, hence they are most receptive to new ideas and cultures. With enough time on their side as far as becoming properly adapted is concerned, I reckon it wouldn't be much of an issue to fully assimilate them into the Singapore society at large.
