My family and I sent an address change request via webform 3 weeks before our oath.
At the ceremony the official asked us to confirm our address and we told her we had moved to a new place recently. She then took our new address and said she'd update it in the system.
So far nothing bad has happened

and we're waiting to receive our certificates in 4-6 weeks.
Good luck to you!
