Applied 8/20
Conditional 10/28

I applied for family 2 weeks later 9/3, so still waiting for their approval. Some questions -

1. Do i have to wait for their conditional approval and schedule interview together?
2. How do i schedule interview together with the family when ids are different?
3.Any tricks to get a sooner interview date , i believe just need to keep checking the page few times in a day?

Also, i assume nexus could be used for Global entry as well. Are there any additional steps which i need to do to use it for global entry?
