What must John obtain to support his claim for good cause in his late appeal?

To substantiate a claim for good cause in a late appeal, it is essential for John to provide compelling evidence that can demonstrate the circumstances leading to the delay. When considering the scenario in which he stayed at a shelter, a statement from that shelter can be particularly valuable. Such a statement could detail the circumstances of his stay, any obstacles he faced while there, or specific events that hindered his ability to file the appeal on time. This context is critical in establishing that there were legitimate barriers preventing John from adhering to the standard timelines for his appeal.

In contrast, while the other choices might provide information about different aspects of John's life, they do not directly address the need for evidence related to the specific circumstances that caused the delay in his appeal. Therefore, a statement from the shelter directly ties to the claim of good cause, making it the most relevant and supportive material in this context.
