does anyone know how to apply for dual citizenship if born prior to 1977
This probably applies to you - see whether it does by implication:
"a person who ceased to be citizen as a minor (under 21years of age) between January 1, 1947 and February 14, 1977 when their responsible Canadian parent took up citizenship in another country or renounced Canadian citizenship, and wishes to resume under subsection 11(1.1) of the Citizenship Act. "
Please find below the CIC link with information on the steps that you should take. When reading the extensive information, please NOTE that
"[the] permanent resident and residence requirements do not apply to you if you lost your citizenship as a minor and you are applying to resume citizenship under subsection 11(1.1) of the [Citizenship Act]."
A portion of the information will not apply to you, but it is strongly advised that you read all of the information in order to glean and highlight which sections pertain to your situation. Also, in case you wonder about section 9, it might not apply to you, and if it does, you can always consult a Canadian Consular office within the U.S. for additional information.
