At most regionally accredited schools in the US, the credits do not expire. They stay on your undergrad transcript forever. It is the degree requirements that expire. And it is the transferability to other schools that degrades. You need to investigate this further. It may be that your credits did not expire, but your degree plan did, and most of your previous credits would still be usable for an updated degree plan.

Otherwise, tell us what school expires its credits, so the community can avoid it like plague.
