So my husband applied in May and everything was processed within 3.5 months. Also, you can expedite the passport, he had to travel as well and he paid a fee and got it within 3 business days. This is mentioned on the website so I know this works. Also, I think the oath invite comes in closer to the oath date. His timeline was basically 1 week after LPP cleared, he got his oath invite for the week after. I think the current delays are due to the holiday but I am expecting things to pick up. I have booked a date for my EU visa for 3rd week of Jan (the country I am applying to processes them within a week, I had applied in 2023 with them). Just tired of getting EU visas, this will be my 5th time :/ really hoping the passport comes through!
