The Deputy may be aware that there is comprehensive information on immigration permissions on the Immigration Service website - www.inis.ie
However, for the ease of the Deputy, I can advise that 'Without condition as to Time' (Stamp 5) is placed in the passport of an individual who has completed 8 years (96 months) of legal residency in Ireland. The stamp is valid to the expiry of the non EEA passport in which it is placed. Applications are only accepted from applicants, whose current permission to remain is due to expire in the next six months. Student permission to remain in the State is not reckonable for this scheme. As this is a Ministerial scheme, successful applicants must not have come to the adverse attention of An Garda Siochana, or be an undue burden on the State.
The holder of a stamp 3 is permitted to remain in Ireland on the basis that they are dependent on another person who is lawfully resident in the State. The holder of a stamp 3 permission is not permitted to work or claim any State welfare benefits. For example, a Stamp 3 permission can be issued to a dependent person of a Non EEA national who holds a work permit in the State. After 8 years they may apply for Stamp 5 permission to remain in the State in their own right.
