If there is a protective filing date, mark the protective filing block. For information
on written protective filing, see SI 00601.020. For information protective filing by oral inquiries, see SI 00601.025.
NOTE: If we issued a closeout notice for the protective filing date, and the claimant
submits an application form after the protective filing closeout period, then we cannot
use the protective filing date as the filing date. However, if an open protective
filing exists, use that date.
