My daughter, who is a college student with little income to her name, got that in the mail, with an RSVP code. What are the chances she will get rejected if she actually applies?
I just finished school myself and have had the Platinum card throughout my time at the University of Minnesota. Then again, I took special care to build a sold credit history and read lots of flyertalk. All depends on what your daughter's credit score is and what kind of credit she has...
And yeah, my income was tiny too.
