A wrap around information sheet accompanies every visa application form. That sheet makes it clear to the applicant that, in general, persons granted visas for particular purposes are not permitted to involve themselves in any activity or to remain in the State for any purpose other than that for which the visa was granted.
Every visa applicant is required to state on the application form the dates on which he or she proposes to enter and leave Ireland. He or she is also required to declare that the information supplied is correct and complete.
A C visa is granted for visits of less than 90 days. As a consequence, it is not the general policy to extend permission to remain to persons who are admitted initially for a period of 90 days or less on a C visa, save in very exceptional and unforeseen circumstances. However, applications to extend permission to remain in such cases — supported by reasons underpinning the inability to comply with the prior existing commitment — should be made in writing to the immigration division of my Department.
