Singapore is the most expensive city in the world for an expatriate professional migrant to live in as at October 2018, followed by Luanda and Hong Kong.
An expatriate is a “professional migrant”, someone who voluntarily lives outside their country in order to take up a job opportunity and a better or at the very least a similar, quality of life. An expatriate professional migrant is different to an immigrant in that they intend returning to their home country and do not therefore consider themselves to be local in their host country.
