Here is my timeline for getting green card based on NIW (EB-2) category with Ph.D.
I applied for I-140 on May 29, 2018, which was approved on Sept. 19, 2018.
Separately, I applied for I-485 on July 10, 2018 with both I-131 and I-765, which was approved on Dec. 17, 2018.
Fingerprint was completed on August 16, 2018.
Interview was scheduled on Feb. 14, 2019.
I-485 was approved on Feb. 14, 2019 and received physical green cards on Feb. 22, 2019
That is all of my story to get green card.
