Before you travel
Arrange the training course
You can attend a training course in Ireland for work or professional development for up to 90 days.
The training course must be on a 'company-to-company' basis. That is, your attendance must be arranged (and/or paid for) by a company you work for or an organisation you belong to.
When you travel
Prepare for border control
You will need to prove that you have a valid reason for entering Ireland to an immigration officer at border control.
To do so you will need your passport and several other documents, eg proof you are enrolled on a course.
If you cannot satisfy the immigration officer, you will not be allowed into Ireland.
During your stay in Ireland
Travel to Northern Ireland & United Kingdom
If you intend to travel to Northern Ireland, check with the United Kingdom authorities if you need a visa.
Leaving & returning to Ireland
If you plan to leave and come back to Ireland during your stay, you will have prove to an immigration officer that you have a valid reason to re-enter Ireland every time you return.
Make sure you have any necessary documents with you for your return journey, before you travel.
