The government of Canada through Immigration, Refugees and Citizenship Canada (IRCC) has issued a statement on the process of study permits (student visa) that will be applied or have applied before March 15, 2020 for those Students who due to the closure of the Visa Processing Offices (VAC) cannot complete the entire application package
Once you have applied online through the IRCC page, the immigration officials will carry out the process in 2 stages.
Stage 1: They will review your eligibility. At this stage the officers will check if you have included in your package the letter of acceptance (LOA) from a DLI institution. If you applied for Quebec, the Certificat d’acceptation du Québec ( CAQ), proof of financial resources, shows that the student will return to his / her country of origin after completing their studies.
Stage 2: They will verify your application for admissibility and any changes to your eligibility. At this stage the immigration officer will review the medical examination (if required), criminal record certificate (if required), biometrics. If your application passes this stage, your application will be approved.
The idea of this process is to avoid delays or backlogs in the VAC centers that have been closed. Once the VAC offices open their doors in your country of origin, you will be able to send your passport so that they can issue your study permit.
