Don't worry, processing has no rules :D
I submitted my application on 12th December too and I had only schedule 4 and 4A request...
Let's hope for the best :)
Don't get nervous buddy... Just take it easy and review your documents and forms many times to make sure everything is consistent and OK.
You still have time till 13 January, so don't panic..
All my best wishes :)
Congrats, Wishing you a quick and successful processing time.
I applied 12 Dec, and I got an email that my profile was updated. I found that my application status became opened instead of invitation received. Did you experience the same?
I asked my photographer to send me the photos on that format with these dimensions. You may do the same or scan your printed photos at 600 dpi resolution and save it as jpeg.
You have to check the requirements as shown on the website. If you haven't received your ITA yet, I can list all the details for you to get prepared.
N.b. Photos have to be taken maximum 6 months ago.
Best of luck
