Hello,
Thank you for your email requesting appointment for minor passport renewal services. Please be advised that due to high demand in passport services and the precautions in place to help prevent the spread of COVID-19, we are unable to offer you an appointment at this time. Currently all our appointments for minor passports are filled until January 2021 and we have not opened our February appointments. Your name has been added to our wait list and we will contact you should an appointment become available.
If your U.S. passport request is because you have a pending Canadian immigration application, please see the Government of Canada’s webpage for guidance on how they are processing cases for applicants who cannot provide a valid passport due to COVID-19 related problems.
Regards,
American Citizen Services (ns)
