We just log in periodically whenever we remember to check on the status. It hasn't moved and he won't get it in time for his international trip, so he is no longer planning to use it.
If he gets approved while he is out of the country, I may help Mom apply and hopefully, they can do their interviews upon re-entry into the US. Otherwise, we will forget it exists.
My immediate family of 4 all got conditionally approved within 48 hours, some the next morning. And as the 4 of us will be traveling together, it will be very convenient!
