I have been issued with a D visa. Can I leave Ireland and return using this Visa?
If the number of journeys indicated on your visa is '01' then you can only enter the State once on this visa. When you have registered with the Garda National Immigration Bureau (GNIB), you can then apply for a 'Re-entry Visa'.If you apply for a multiple journey re-entry visa, it will be valid from the date of issue until the expiry date on the Registration Card issued to you by the GNIB, or the expiry date of your passport, whichever is earliest.
This will allow you to leave and re-enter the State any number of times within the dates shown on your visa.
If you apply for a single journey re-entry visa, this will only be valid for one entry to the State within the dates shown on the visa, which will be for 90 days from the date of issue. (It will not be valid for the duration of your GNIB card).
To avoid having to apply for further visas for the duration of your permission to remain, you should apply for a multiple-entry re-entry visa.
Please check Re-entry Visas for further information.
