Singapore is a multi race country if those pr and news citizens only able speak in their own language it will cause social fracture. Where they only want to integrate with their own kind of people of origin. Plus it causes lot of fiction among the society.

Nus is a very good example.  Many ceca there speak English too. But these people only clique among themselves. How to integrate?
My son said never ever get near to them, the whole gang will look at you suspiciously.
You probably need to wait for their second or third generation for them to integrate.
