If you hire an overseas worker on an employment permit, there is a point down the line where they no longer need that permit at all. They reach Stamp 4. For you as the employer, that milestone changes the paperwork, the cost, and the retention maths — so it pays to understand it before you make the offer, not after.
This guide is for the person signing the permit application: what Stamp 4 is, when your worker becomes eligible, and what actually changes for your business on the day it happens.
What Stamp 4 actually is
Stamp 4 is an immigration permission granted by Immigration Service Delivery (ISD). It lets a non-EU national live and work in Ireland without an employment permit.
That last part is the whole point. A worker on Stamp 4 can:
- Take up any employment, with any employer, without a permit
- Change jobs or roles freely
- Be self-employed or start a business
- Access services on broadly the same footing as an Irish resident
It is not permanent residence and it is not citizenship. Stamp 4 is time-limited and has to be renewed — a Filipino care worker who reaches it through a General Employment Permit renews yearly; one who reaches it through Critical Skills renews every two years. It counts toward the five years of reckonable residence needed to apply for citizenship, but it is a step on that road, not the end of it.
For your purposes, treat Stamp 4 as the moment the permit system lets go of your worker. Everything below is about when that happens and what you do about it.
Why it matters to you
Most employer guides stop at "get the permit". They should not. The permit is a fixed-term arrangement, and the day it stops mattering is a real event you can plan for.
Three things change at Stamp 4, and each one hits your business:
Cost. You stop paying to renew the employment permit. No renewal fee, no renewal application, no waiting on a DETE decision to keep someone you already employ.
Flexibility. A permit ties the worker to a specific job with you. Stamp 4 removes that. You can move them into a different role, change their duties, or promote them without touching a permit — because there is no permit.
Retention. This is the one that catches employers out. On a permit, a worker who wants to change employer has to go through a formal process and a waiting period. On Stamp 4, they can walk into any job in the country. The leverage the permit gave you is gone. If you have not built a reason to stay by then, you can lose a trained, settled worker to a competitor down the road.
Knowing the timeline lets you get ahead of all three.
The Critical Skills route: 21 months
If you hire on a Critical Skills Employment Permit — think senior nurses, ICT specialists, engineers, roles on the Critical Skills Occupations List — the route to Stamp 4 is short.
Your worker can apply for a Stamp 4 upgrade after 21 months of employment in the State on the basis of that permit. ISD measures the time from when they actually started work, confirmed through their Employment Detail Summary on Revenue's system, not from the date the permit was printed.
A Critical Skills permit is usually granted for two years to begin with. Line that up: the worker becomes eligible for Stamp 4 at 21 months, before that first permit even expires. In many cases you never renew a Critical Skills permit at all — the worker upgrades straight to Stamp 4 instead.
One more change worth knowing. Since 30 November 2023, the Stamp 4 support letter that the Department of Enterprise used to issue is no longer required. The worker applies directly to ISD. It is a cleaner process than it was even two years ago.
The same 21-month threshold applies to researchers on a Hosting Agreement and to non-consultant hospital doctors on a Multi-Site General Employment Permit.
The General Employment Permit route: 57 months
Most of the roles we place — care assistants, farm and dairy workers, chefs, general operatives, most construction and hospitality roles — go through a General Employment Permit. The route to Stamp 4 here is longer.
Your worker can apply after 57 months of employment in the State on a General Employment Permit. That is just under five years. The same 57-month threshold covers Intra-Company Transfer employments.
Five years means renewals along the way. A General Employment Permit is typically granted for two years first, then renewable. So a long-term General Employment Permit hire will usually go through one or two renewals before they ever reach the Stamp 4 milestone. That is normal, it is manageable, and it is a cost you should factor in from day one.
The two routes do not mix. Time spent on a General Employment Permit does not count toward the 21-month Critical Skills threshold, and vice versa. If a worker moves between permit types, the clock is read against the permit they are actually on.
What changes once they hold Stamp 4
The day the Stamp 4 registration is issued, a few practical things shift for you:
- No more permit renewals for that worker. The employment permit is no longer part of the relationship.
- No job-description lock. You can change what they do without a permit amendment.
- They can be promoted or moved into a role that would not itself qualify for a permit — it no longer needs to.
- They can legally take on other work, including for other employers. That is their right now, not something you control.
Nothing forces the worker to leave. Plenty stay for years — Ireland is home by that point, and a good employer is worth keeping. But the choice becomes entirely theirs, and that is the part to plan for.
The permit years are your retention window
Here is the practical takeaway. The years your worker spends on a permit — two years for a Critical Skills hire, close to five for a General Employment Permit hire — are the window where the immigration system keeps them anchored to you. Use them.
The employers who hold onto overseas staff after Stamp 4 are the ones who treated the permit years as an investment in the person, not just a hiring hurdle. Fair pay above the minimum. A real path to more responsibility. Help settling in — accommodation sorted early, family reunification supported where it applies, a workplace where a worker from Cebu or Manila is not the odd one out. Do that, and Stamp 4 becomes a formality rather than a resignation letter.
At CA Recruitment we place Filipino workers with Irish employers and manage the whole permit journey — the first application, the renewals, and the planning for the day the permit stops mattering. Monette founded CA Recruitment having gone through the Irish immigration system herself, so this is not theory.
