Interview Waivers At their discretion, visa officers may approve an application for permanent residence in Canada without holding a selection interview. An interview waiver will significantly expedite the processing of the application. Usually, well-prepared applications, which are complete in every detail will increase the chances of an interview waiver.
When assessing an application under the Skilled Worker category, visa officers will consider several factors before granting an interview waiver such as:
Quality and completeness of the application forms and documents
Proof of the applicant's English and/or French language ability
The applicant's educational qualifications
The applicant's professional qualifications such as quality of his/her educational background and work experience
The applicant's potential for adaptability, resourcefulness and motivation to successfully establish himself/herself in Canada
The applicant's overall integrity and credibility
Nevertheless, a selection interview may occasionally be required for even highly qualified applicants, as Citizenship and Immigration Canada (CIC) officials randomly select such applicants to test the accuracy of their interview-waiving criteria for quality assurance purposes.
Rarely, it is also possible that after an interview waiver has been granted, the visa officer may change his/her mind and require the applicant to come to the selection interview or vice versa.
but generaly interview is very easy and takes 10minutes maximum.
