I applied online on September 4th-the day I received Global Entry final approval.
I also applied online for my two children, who also received their Global Entry approval. These applications were completed one after the other.

A few hours later, submitted application for my wife. She does not have Global Entry.

November 8th I received conditional approval as did my two children.

My wife has not yet been approved.

November 9th was the first available interview at Champlain, New York. I plan to be up there towards the end of December, so I booked three consecutive appointments. Hoping my wife's application will be approved soon enough to book an appointment at approximately the same time.
