Here's an update. Just received an email from the Board informing me that they cannot proceed with my application until they receive my record of cases. Since it is now impossible for me to provide the said requirement, I asked if I can just take additional coursework here in CA to make up for the lost cases. They said they won't recommend it until the Board formally advises me of a deficiency. But since my application cannot proceed, they will not be able to determine the deficiencies and my eligibility to take the exam. So in other words, I just hit the dead end for my application.
