We move quite a bit and my kids have applied to colleges with DE credit from more than one state to OOS schools. Their DE credits have been accepted. Our youngest ds had to submit course, textbook, and syllabus info to one dept, but the courses were approved for credit. Other times it has been a non-issue and credit was awarded immediately. Most of the classes have been from 4yr to 4 yr universities. One dd did transfer credit from an OOS CC.
When in doubt, make direct inquiries about how the individual institutions handle DE credit. There is not a single answer.
