This is not 100% accurate, we’re just talking statistics.
You need to count 70 days after November 22 to receive the letter inviting you to the oath. I’d say the first week of February. This letter will invite you to take the oath two weeks later. As such I’d estimate that you’ll take your oath the third week of February. Maybe around the 20th or so.
Again, tho is based on statistics. The end of year vacation will probably lead to further delays. So take this all with a grain of salt.
If I was in your shoes, I’ll mentally won’t expect any oath letter before February. This way you enjoy the coming couple weeks stress-free.
