Over a twenty–year period, organized groups of concerned citizens regularly met with Canada's Prime Minister and Immigration Minister, bringing attention to the devastating reality of family separation in Chinese Canadian communities. Wong Foon Sien was a prominent voice in this movement, lobbying Ottawa annually. In 1957, the lobbying party included one woman, Jean Lumb, who represented women's interests. These efforts secured hard–won changes to immigration regulations, allowing more Chinese Canadians to sponsor a wider range of family members, notably unmarried offspring, husbands and wives, and elderly parents.
