A loan/credit, either personal or car, or house or plastic (credit cards) or any type is a loan.

In the end not being able to pay it back carries the same risks on all of them. Defaulting on a loan or  a credit card is not good since it could end in a legal case against you. And in the ME it could lead to jail time and deportation with the respective BAN to that person.

Once again the risk is similar to any loan/credit not being repaid.
