Salams Rabia. Firstly, Congrats. Your AOR came just in 19 days. Most of applicants, prior to April 2023, their timelines show atleast 2 months lag between Submission and AOR. Your is only 19 days!! Checking the timelines of different participants on this forum, Sponsorship approval usually comes follows AOR by 1-2 days, may be a week in some cases. Along with it will be Biometrics and Medical request as well, i guess. Its been months - yes i'd get concerned too.
Yes you have applied through consultant - but you should still be able to get information about your application - as you are the principal applicant, right? Your husband should call the CIC center, provide your UCI, should ask details of how you can get access to progress of your application.
