a passport valid at least until the expiration date of the relevant working visa or work authorisation;
a photograph and
a visa application fee of IR£40 [€50] or equivalent (not charged in the case of a number of nationalities) or a work authorisation application fee of IR£29 [€36] or equivalent.
An applicant who is a nurse must also present a certificate of temporary or full registration issued to her/him by An Bord Altranais (The Nursing Board).
