Me and my son applied for naturalisation via Tier 2 General + 1 year ILR route. I have received one approval letter via email on 30/11/2020 saying that
This will not affect XXX XXX application as he does not need to attend a
ceremony. His certificate will be sent directly to you within the next four
weeks.
Promised four weeks has passed while ago and still no certificate was received. Is this normal during pandemic? Is there any route to enquire about overdue status? (I would also like to enquire about myself as it's been awhile since email was received and there were no correspondance via post).
