(1)asked to provide a finger print from his home country... (2)the Canadian finger print to shorten his application processing time.
1. There is nothing called 'fingerprint from home country". At best it'd be a PCC requirement, which the applicant already knows is a requirement while applying for Canadian citizenship ~ and should provide one
with his/her application. Viz. "living 183 days and above in any country other than Canada". Meanwhile, FP request is an inland thing. Which not everyone is asked to submit.
2. Nothing can "shorten" our processing time. We can at best curtail it's additional timeframe by submitting a correct and complete package to begin with ~ and submitting the required docs (if asked) as soon as possible, which absolutely should be within the timeframe it has been notified to (by the additional docs request letter sent by IRCC, which will
not be for everyone).
