SDS Category stands for the Study Direct Stream category of the Canadian student visa. It is a streamlined visa processing program that aims to make the application process faster and more efficient for eligible students from specific countries, including India.

To apply for a student visa under the SDS category, the applicant needs to provide the following mandatory documents:

1. Acceptance letter from a Designated Learning Institution (DLI)
2. Proof of payment for the first year of tuition fees
3. English language proficiency test result with a minimum score of 6.0 in each module of IELTS, or equivalent scores in other approved language tests
4. Guaranteed Investment Certificate (GIC) of $10200 CAD to show proof of funds to support the student's living expenses in Canada

Besides the mandatory documents, the applicant needs to fulfill other requirements, such as meeting the eligibility criteria, providing valid immigration history details, demonstrating the relevance of the course with their past education, work experience and future goals, and showing employment history up to the current date without gaps.

To ensure accurate supporting documents and details for the visa application, you can create a manual that outlines the necessary steps to follow. The manual should include the application process, required documents, eligibility criteria, and other relevant information. It's crucial to seek expert advice before submitting the visa application to increase the chances of approval.
