families did not lose their identity as easily. An example would be Southall which is populated by many Sikhs. During the same time, medical staff from the Indian subcontinent were recruited for the newly formed National Health Service. These people were targeted as the British had established medical schools in the Indian subcontinent which conformed to the British standards of medical training. Bengali social reformer and founder of the All-India Seamen's Federation, Aftab Ali's work is recognised to have helped thousands of Asian lascars to migrate, settle and find employment in Britain. He organised rallies and meetings with the likes of the Trades Union Congress. He encouraged lascars and seamen to remain and settle in the United Kingdom. In the 1950s, he founded the Overseas Seamen's Welfare Association which campaigned distressed seamen and their families to be granted British passports. Ali also played an instrumental role in the opening of a passport office in his own home in Sylhet. Asian migration from East Africa Beginning around 1964 Africanization policies in East Africa prompted the arrival of Asians with British passports from Kenya, Uganda and Tanzania. At first these were the people employed in government and administrative roles, but this was expanded to include those Asians engaged in commerce. The movement was called the "Exodus". In 1972, all South Asians were expelled from Uganda by the controversial figure Idi Amin, then president of Uganda. Those holding British passports came to Britain. Many such displaced people who were predominantly of Gujarati origins had left behind successful businesses and vast commercial empires in Uganda, but built up their lives all over again in Britain, starting from scratch. Some of these "twice-over" migrants became retailers, while others found suitable employment in white-collar professions. The Commonwealth Immigrants Act 1962 and Immigration Act 1971 largely restricted any further primary immigration, although family members of already-settled migrants were still allowed. In addition, much of the subsequent growth in the South Asian community has come from the births of second and third-generation South Asian Britons. Notable contributions Arts and entertainment Several Asian Britons have broken into the UK film industry, as well as Hollywood, and the U.S. film industry at large; starring in high-grossing box office films, including major film series, and receiving subsequent international recognition and media attention. In television, prominent roles in American sitcoms, series, and long-running British soap operas, such as Coronation Street, EastEnders, Emmerdale
