I see that you are an expert in the field and that you enjoy reading your answers to other people`s questions. My wife and I have been Canadian citizens since the mid-1990s, but we have lived in the United States since the late 1990s. While I was earning income in the U.S. and accumulated 40 Social Security credits, my wife has an income from work in the U.S. and has lived in Canada for about 4 years. Could his 18-year-old residence in the U.S. be used to help him meet the 10-year Canadian residency requirement or the 20-year residency requirement outside of Canada for AEO benefits? Is the AEO benefit approximately 578$US per person or per couple? Is there a possibility or risk that the OAS will be reduced/eliminated in the future, especially for Canadian citizens who have qualified for a significant amount of the Social Security benefit in another country such as the United States? Does Service Canada have an agreement that national insurance premiums (paid in the UK) can be set off against their 20-year requirement, or do you have to live and work in Canada for 20 years to get OAS abroad? Meeting these minimum contribution requirements is generally not difficult if you have lived in Canada all your life. . .
