Called CIS regularly after PD became currently this June. Was told conflicting answers about NC and clearances. Infopass twice - useless. Wrote to Congressman and FL, and very recently to FBI. Maybe one or some of these measures worked, who knows. But at least the congressman's office was kind enough to respond and follow up on the case.
NOT ALL HOPES ARE LOST. Best of luck to those who are still waiting.
Have learned some much from this forum. Thank you, especially to those who responded to my questions/posts.
