My 'person' wasn't born in the United States. As for cancelling...it might be as simple as:
A scenario might be like this: Document gets sent by certified mail, copy filed with certificate of service in a Misc. Jacket or libel of review at the US District Court nearest John H. Doe. After thirty days a certificate of non-reponse/default goes to SSA and to case jacket. Follow up with reassertion that the account is cancelled and demand that all 'applicant information' (specific term used by the SSA) be deleted. You get the idea? Whether the cancellor/fiduciary (rhymes with chancellor) or one having authority is or isn't a person born subject to the jurisdiction of the United States --or is or isn't a resident of the United States might have a lot to do how well it goes.Comes now John H. Doe, with full authority, with full right, for sincere and lawful reasons withheld, being unaware of willingly or knowingly applying for any benefit, account or card provided by or through the Social Security Administrating, now having full authority and power over JOHN HENRY DOE, TEXAS BIRTH OR FILE 1494195858 do hereby cancel any and all applications for any accounts, social security cards or benefits provided by or through the Social Security Administration.
If anyone has any questions or comments concerning this Cancellation they must make them known within thirty days by....

If there are any outstanding bills or the like in that persons name, it might be very good idea to pay them first.
There might be some 'cleanup' issues with banks, DMV, etc.
In other words, if you want to eat-> you eat (rather than merely talking about eating). If you want to cancel you cancel. Pretty simple eh?
