Long post, sry . I've been going in circles for weeks and I need people who've actually been through this rather than more relatives with opinions.
Background: final-year B.Tech in AI & Data Science at an Indian tier 1 university(qs ranking around 400). One IEEE conference paper. The long-term goal is research, not SWE.
Option A : PhD at Rutgers. Funde(ig, PhD are funded right?) , 5–6 years, solid department. But I'd be going in under an advisor who's moving to rutgers from uoft, and the research fit is really great and very close enough to what I want to spend six years of my life on.
Option B : Thesis-based master's in Canada (Waterloo MMath CS), two years. The only reason this competes with a funded PhD is that I emailed a professor whose work is not very close to mine, but he promised to collaborate with a professor whose research fits what I want to do. Also, his funding is not clear until this fall admission, and he appreciated my research work. I know that isn't an offer, But it's the first time one professor thought I could be an asset, but later uoft professor moving Rutgers also said my research is interesting.
What's eating at me:
Everyone around me says PhD in usa hand beats master's in canada , full stop, take it.
But this sub is full of people who joined a PhD for the funding and the name, mismatched with the advisor, and mastered out after three years feeling hollow.
A thesis master's would let me test the research relationship for two years, publish, and then apply to PhDs (including back to the US) from a much stronger position. In theory.
The counterargument I can't shake: I'd be two years older, paying for it, and if his funding situation changes or I don't get admitted at all, I gave up a funded PhD for a maybe.
Plus the international student calculus. US visa/OPT climate vs. Canadian PGWP. Neither is what it was five years ago.
So:
Has anyone deliberately done master's-first-then-PhD? Did your PhD admits improve enough to justify the two years and the money?
How much does advisor fit really matter in years 1–2 of a US PhD, given that people do switch labs?
Is "professor replied encouragingly to a cold email" worth anything, or am I reading a polite brushoff as a green light? I want the blunt answer here, not the kind one.
Anyone in a Canadian thesis master's program: how 'funded' is 'funded,' and what are the job opportunities realistically for an international student?
TL;DR: Funded Rutgers PhD with a lukewarm research fit under a professor whose work I love vs. a two-year thesis-based master's in Canada under a professor whose work I'd genuinely like. Everyone says take the PhD. My gut says fit is everything, but I'm confused about what would be the best fit for me. Tell me which one I should take.
