Here is my time line and experience.
My CN current the 1st month of the 2019 fiscal year. It's been a long wait in every step of the process totally from start to finish took 8 months to get approved. I believe because of the workload of my field office. It took 2 month to get and IL, then got reschedule for another 2 and a half to get new interviewed date. Then , 3 more months to get approved. However, I got an email notice the card was ordered. Hope this info helped you guys calm down a bit and be on top of the process. Thank you everyone here for the guidance and many great advice.
Best,
PT
