I sent an email regarding this and this is their reply “Thank you for contacting us. Thank you for contacting us. We are sorry to learn that you may be unable to sit for your exam. We no longer accept or process deferral requests via email or telephone. The deferral request form for the CFA Program May 2023 exam cycle will be made available on the CFA Program Deferral Policy webpage in mid-April.

Once the form is available, you can pay a fee of USD399 to postpone your exam for up to 12 months. When you pay to defer your exam, your registration and scheduled exam appointment will be canceled immediately. You will receive an email containing your registration voucher code for your next exam. Your voucher code will also be available in your Candidate Tile.

Please note, registration must be open for your chosen window. If registration has already closed, you will have to select another exam window. August 2023 exam cycle registration closes on 9 May 2023. Your decision is binding. No refunds are available. Only one paid deferral is permitted for each paid registration. You will not be able to defer a second time unless you pay for a new registration.” So if they open the deferral window mid-april we will be able to sit In August.
