I applied for a renewal on April 13, 2019, and when I flew back into the US from Istanbul last week, it was still not approved. I was directed by one of the immigration officials to the Global Entry desk in immigration, where the agent was not busy. She checked and told me that it was still "pending", and that with so many DHS agents being called to the border, they have been informed that a 5-month timeframe for renewal approval is the "norm". Who would ever have imagined that a renewal would take 5 months when it is just straightforward?
