Thank you, you mean to contact Cic through web form?
Yes, most of the people who I had recommend to do so have got success.
Usually they respond only if your application has passed normal processing time.
But at times some applicants have got success with the link by requesting Oath after decision made.
Some have got success in getting decision made upon request when their application was stuck in in-progress.
Though one thing you got to remember, your Security and Background clearances have to be completed before they make a decision.
Do not expect to use this form if you have just applied or not completed your Citizenship Test unless you have a Job offer that requires you to be a Citizen or something like that.
