Migrating to Canada without taking the IELTS through an agent can have several disadvantages. Firstly, the IELTS is a recognized language proficiency test that assesses an applicant's ability to communicate effectively in English or French, both of which are essential for successful integration and communication in Canada. Without a valid language test score, immigrants may struggle to find employment, access social services, or participate fully in Canadian society. Additionally, not taking the IELTS may limit the individual's eligibility for certain immigration programs and reduce their chances of receiving a favorable application outcome. Ultimately, bypassing the IELTS requirement could hinder the overall success and adaptability of the immigrant in Canada.
