Student Direct Stream (SDS) is a faster study permit processing route (around 20 days vs 3-6 months regular) available to students from India, China, Philippines, Vietnam, Pakistan, and several other countries. Requirements include admission to a DLI, IELTS 6.0 minimum in each band, GIC, proof of first-year tuition payment, and medical exam upfront. SDS significantly reduces processing time and has slightly higher approval rates, so use it if you’re eligible. However, it requires full upfront payment, so ensure you’re committed to the university.
