Update:
Gathered all materials I could think of, had blank forms and extra copies of everything. Went to the Los Angeles passport office on Monday 5/14, and everything seemed to go very smoothly, less than an hour. 3 people including a supervisor checked all of my son’s paperwork. Paid to have expedited and were told we could pick up Friday. Wednesday, received call that his statement and itinerary, which had been checked and handed back to us was needed. Said we could come and drop off an hour before our will call pick up time. Went and in order to drop off, we had to wait in line again and then talk to a senior supervisor. This time it was a lot more crowded. Hours later, we were able to go home with 2 passports! I’m sure it would have been more stressful without the help I received here. Thanks to all who replied. Hopefully this thread will help others who find themselves in this situation.
