I am a Canadian citizen who has lived and worked in the USA for 40 years. I have a green card. Recently, I contacted the Canadian Embassy and was told that I would have no trouble entering Canada with my Green Card. My question is - will it get me back into the USA ? I have a handicapped sister who lives in Windsor, Ont. and I desperately need to visit her. p.s. I am working on getting my passport but need to see her b4 then.
