Thanks for your detailed information.
My case EB3 China becomes current in Sept. My hu*****and called the Friday before last and didn't get any useful information. Last Friday, he called again and was told it's assigned to an officer and under review. However today I recieved a letter dated as the Friday before last and mentioned all security review have cleared and pending review, please call again in 6 months...
I'm very anxious about the I485 approval, have waited for almost 5 years.
