OK let’s cut to the chase...
Ted’s mother was born in Delaware to American parents..
When Ted was born in 1970, was his mother still an American citizen ???
What she did about her nationalities later has no bearing on his eligibility...
It would not have been legally POSSIBLE for Ted’s mother to be a Canadian citizen. They moved to Canada in 1967. Ted was born in 1970. Canada REQUIRES 5 years of residence in order to become a Citizen.
So legally, she could ONLY be a US citizen.
Thanks for that info....does Canada allow Dual Citizenship...might be a good question....
