No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
My suggestion would be to get a new card now and not wait for the account to close. The effect on your husbands credit score will be based on increased utilization. If he still has a balance and that is his only credit card it is likely he will appear to be maxed out (and maybe even over the limit??). However, I am not sure about this. If he appears maxed out on his only card that could make getting a new card more difficult.
If possible pay off the card and get a new one.
Good luck.
