What are the post-study work visa rules in Ireland, specifically about stay-back visa duration and requirements for sponsored jobs for a Master's/Bachelor's?

Yes, Ireland offers a post-study work visa (Stamp 1G) for international graduates.

- Master’s (Level 9) graduates can stay for 24 months (granted in two 12-month periods; the second year requires proof of active job search or employment).
- Bachelor’s (Level 8) graduates get 12 months.
- During the stay-back, you can work full-time (up to 40 hours/week), but self-employment isn’t allowed.

To stay longer, you’ll need employer sponsorship for a work permit like the Critical Skills Employment Permit (minimum salary €40,904, subject to change) or the General Employment Permit. These permits can lead to long-term residency options.
