A little over 2 months from NCS appointment to approval letter and one month wait until the next citizenship ceremony.
For those wondering about dress code for the citizenship ceremony, my letter specifies that formal dress is required and jeans will not be accepted. I'm not sure if this varies between locations.
I plan on applying for my passport straight after my ceremony. Does anyone know how it works with the first-time passport interview? Do you just apply and then wait for them to contact you for an appointment?
