<prompt> Human: My girlfriend is a Colombian citizen and has no US credit, besides utilities on an apartment for 4 months. Since she is not a citizen and has no credit history, finding credit cards is difficult and all seem to require a deposit. I have good credit and a card that I have been thinking about letting her cosign on, to help build her credit. Ive told her the only purchases she would be able to make on it is her rent. Im not worried about her making excess purchases since she is extremely frugal, and she is in a good PhD program for 4 more years so Im not worried about her leaving the country either. She doesnt need the buying power of a credit card since she has enough money, just credit.I realize cosigning is risky, but assuming I completely trust her, is there anything else Im missing? For example if we broke up how easily can I take her off the card? Its a Chase Sapphire Preferred if it matters.  <response>: If you really want to help, you can put up the money for a secured card. You still have the risk of her leaving you high and dry, but presumably the security amount would be less than the full credit limit of a co-signed card, so you would lose less.
