Are there courses in Canada or Ireland that offer post-study work visas based on the duration of study for a PhD?

Yes, both Canada and Ireland offer post-study work visas, and the duration depends on your study program's length and level.

In Canada, the Post-Graduation Work Permit (PGWP) allows you to work after graduation:
- 8 months to less than 2 years: PGWP matches your study length. - 2 years or longer: PGWP valid for up to 3 years.

In Ireland, the Third Level Graduate Programme (Stamp 1G) provides:
- Bachelor’s (Level 8): up to 12 months. - Master’s/PhD (Level 9/10): up to 24 months (12 months + possible 12-month extension).

Longer or higher-level programs lead to longer post-study work visa durations.
