How to obtain a work permit:
When a hiring manager offers you employment at the interview, provide them the permit application form (B1-1) and have them complete the "employer" portion, which includes their signature. Then, give the form to your parent to sign and approve the job placement, and finally, you complete the top and sign the form. At that point, you are ready to look at the calendar.
The calendar has the emails of all of the coordinators working this summer, by day. When you are hired and your form is complete (with all 3 signatures), email the coordinator to make an appointment for a work permit.
