Status Update:
Nexus Application Date for minor kid who is a US citizen and Canada PR: June 26th
Conditional Approval: Dec 10th
Interview Date: Luckily got Dec 24th in Blaine as many appointments were cancelled during the holiday time frame
Nexus Card awaited now

Wife's conditional approval is still awaited so I did ask the officers during the interview. They just said it could be anything between 3 months to 20 months so just wait :(
Status Update:
Wife's application also approved finally. She had applied on Oct 8th and approval received on May 23rd. Luckily got an appointment on May 27th as well.
 
Do you need to face the customs officer (CBP) when entering the US with a Nexus card?
