It depends on if they were added on as an authorized user or as a cosigner. If you just give permission for someone to use the card, then it will not appear on their credit report. However, if they sign on the card and agree to take responsibility for repayment, then it should appear on their credit report.
If you sign for the card, they should ask for a social security number. My guess in your situation is that they were just added on as an authorized user.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
