There is a Whatsapp group set up by several former interns (and now close friends) - to have meals with me when I visit Singapore. We meet and eat, and talk about their lives there, and their plans for the future. I tease them about how much money they are making, that they should treat me to more meals when I visit.
The 3 of them are amongst many Malaysians who decided to work in Singapore. Many leave after obtaining their degrees for the higher pay and favourable exchange rate and never return. Even when they leave Singapore, many do not return to Malaysia.
