The real return on a foreign degree is not the certificate — it is the years of paid work you get afterwards in a higher-wage economy. Each destination's post-study work rules are different in ways that materially change the financial case.
Post-study work visa rules are among the most-changed pieces of student immigration policy. The structures below have been broadly stable for the last 2–3 years, but durations, eligibility, and PR pathways can change with limited notice. Verify the latest before making a country choice based on these rules.
United Kingdom — Graduate Route
The Graduate Route gives international students a 2-year unsponsored work visa after completing a bachelor's or master's degree at a UK university on the Student Sponsor list. PhD graduates get 3 years. No job offer is required to apply — you transition from your Student visa to the Graduate visa from inside the UK.
You can work in any role at any skill level (including self-employment), but the Graduate Route does not lead directly to settlement. To stay long-term, you typically need to transition into the Skilled Worker visa during or at the end of the 2 years — which requires sponsorship from a Home Office-licensed employer at a minimum salary (currently £38,700 for most roles, lower for some shortage occupations and new entrants).
Australia — Temporary Graduate visa (Subclass 485)
The 485 visa has two streams. The Post-Higher Education Work stream (most common for Sri Lankan students) gives 2 years after a bachelor's degree, 3 years after a master's by coursework, 4 years after a master's by research, and 4 years after a PhD. The Post-Vocational Education Work stream gives 18 months after eligible VET qualifications.
Graduates of regional Australian universities get an additional 1–2 years on top of the base duration. Like the UK, no employer sponsorship is needed for the 485 itself. The 485 is also the stepping stone for the points-tested skilled visas (Subclass 189 independent and 190 state-sponsored) — the main pathways to Australian permanent residence.
Canada — Post-Graduation Work Permit (PGWP)
The PGWP is an open work permit valid for a length that matches the duration of your study programme, up to a maximum of 3 years. An 8-month diploma gives an 8-month PGWP; a 2-year degree gives 2 years; a 3-year programme (or longer) gives the maximum 3-year permit.
PGWP eligibility tightened in late 2024 — only graduates of programmes at PGWP-eligible institutions in fields aligned with long-term Canadian labour needs (or specific bachelor's and master's degrees) now qualify. The PGWP feeds directly into Canadian permanent residence via Express Entry: the Canadian Experience Class category counts Canadian work experience under a PGWP, which is one of the most-used PR pathways for international graduates.
USA — Optional Practical Training (OPT) and STEM OPT
OPT gives F-1 visa holders 12 months of paid work in their field of study, applied for via their university Designated School Official before graduation. STEM OPT extends this by 24 months for graduates of designated STEM degree programmes — giving a total of 36 months of post-graduation work for STEM graduates.
Unlike the UK Graduate Route or Australia 485, OPT is tied to your field of study — non-STEM graduates have a hard 12-month limit and the path to longer work authorisation runs through the H-1B lottery. The H-1B is the dominant long-term work visa but the annual cap (currently 65,000 plus 20,000 master's-degree-holder slots) means there is no guarantee of selection.
Pro Counsellor Tip
"PSW duration matters less than the PR pathway behind it. A 3-year Australian 485 with a clear path to PR via Subclass 189 or 190 is worth more, financially, than a 3-year USA STEM OPT with an uncertain H-1B lottery."

Compare PSW OptionsPR pathways from post-study work
For Sri Lankan students with long-term residence in mind, the PSW visa is only the first stage. Australia and Canada both have transparent, points-based PR systems where post-study work experience contributes directly to your eligibility — a Master's graduate in a high-demand occupation with 2 years of work experience and decent IELTS often clears the threshold for an Australian 189 or Canadian Express Entry invitation.
The UK pathway runs through the Skilled Worker visa for 5 years, after which Indefinite Leave to Remain is available. The USA pathway requires employer sponsorship for an H-1B, followed by employer sponsorship for an EB-2 or EB-3 green card — for Sri Lankan citizens this is currently a 4–8 year process from H-1B start.
How to choose based on PSW
Three rules of thumb. First, if you plan to come home: PSW duration matters less — pick on programme strength and cost. Second, if you might stay: weight Australia and Canada higher; the PR systems are predictable. Third, if you specifically want the USA: pick STEM and pick employers known to sponsor H-1B aggressively (large tech, finance) — non-STEM in the USA is a much harder long-term proposition than the same degree in the UK or Australia.
