Immigrants Act, restrictions were placed on immigration from current and former British colonies, and these were tightened by successive governments. The Immigration act included a voucher system and significant Chinese migration to Britain did still continue by relatives of already settled Chinese and by those qualified for skilled jobs, until the end of the 1970s. Today, a significant proportion of British Chinese are second or third generation descendants of these post-World War II immigrants. Approximately 30,000 workers from the New Territories were resident in Britain in 1962 and records showed remittances at HK$40 million. Ninety-six wives from Hong Kong joined their husbands in Britain in the beginning of that year, indicating a new phase from 'sojourning' to family reunion and a more settled life. In 1976, Britain's Chinese population included approximately 6,000 full-time students and 2,000 nurses. The 1981 British Nationality Act deprived Hong Kong British Overseas Territories citizens of the right of abode in the United Kingdom, an issue that caused some controversy in the years leading up to the territory's handover to China in 1997. After the Tiananmen Square protests of 1989, it was considered necessary to devise a British Nationality Selection Scheme to enable some of the population to obtain British citizenship to maintain confidence in Hong Kong and to counteract the effects of the emigration of many of its most talented residents. The United Kingdom made a provision to grant citizenship to 50,000 families, whose presence was important to the future of Hong Kong, under the British Nationality Act (Hong Kong) 1990. (See also British nationality law and British nationality law and Hong Kong). In 1981, the Census recorded Britain's Chinese population as 154,363. Thirty-five Chinese-language newspapers and 362 periodicals were on sale from seven bookshops in Soho. Sing Tao itself had a circulation of 10,000 in Britain. The Chinese population now numbered the elderly, and 30,000 children in British schools. Of these, 75 percent were born in the country, representing a new phase of settlement. In 1982, the Merseyside Chinese Community Services opened the 'Pagoda of Hundred Harmony', an advice centre built with the help of an Urban Aid grant. In 1983, the Chinese Information and Advice Centre (CIAC), an amalgamation of the Chinese Workers Group (1975) and the Chinese Action Group (1980) received Greater London Council (GLC) funding for a centre. Sixty Chinese associations, including women's groups and old people's clubs, were consolidated into
