Simon Cheng, from the Hong Kong expatriate group in Britain, said his fellow citizens' decisions to come to the UK depend on age, political involvement and career prospects. He agrees with Home Office estimates of hundreds of thousands arriving over the next five years. They include pro-democracy protesters and people dissatisfied with Hong Kong’s political reality. A small survey of Hong Kongers found that those inclined to move to the UK were mostly working professionals, often in fields like financial services. The Home Office estimates that tax receipts from new arrivals, many likely to work in well-paid sectors, suggest a net benefit to government finances of £2.4 to £2.9 billion over five years. This significant movement of people presents opportunities for the Government, but also challenges it to put in place effective support for the less well-off arrivals.
