University of Waterloo: the honest note
Strong co-op and tech-recruiting culture; PGWP up to 3 years supports a solid migration pathway.
UNSW Sydney: the honest note
Widely marketed by agents; Sydney's cost of living and the 2026 485-visa tightening both cut into ROI - verify actual placement rates independently.
How payback is calculated
Payback = total program cost ÷ (starting salary abroad − ₹8,00,000 India baseline). The baseline rises for IIT/NIT-class graduates, which lengthens payback for those students on both programs above. Full formula and worked example in the payback period guide.
