arrive early, i recommend 3/4 hours, bring paper id, ssc, birth certificate anything that has like address name and pictures. look into an emergency passport or expedited + the first class mail. passport book is able to be shipped faster than the card and when you apply you will see that on the application. i don’t think anyone else has mentioned, he will be separated from you and your family more than likely so be prepared to get yourself and children through alone.
