Carnegie Mellon University: the honest note
Elite CS program with strong FAANG placement. STEM OPT gives up to 3 years of US work authorization post-grad, but converting to H-1B afterward has gotten harder for entry-level hires since 2026 (see visa risk flag).
University of Waterloo: the honest note
Strong co-op and tech-recruiting culture; PGWP up to 3 years supports a solid migration pathway.
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.
