The key elements for success in applying for a study visa for Ireland are:
Make sure all documentation required is in order and complete.
Age: Student applying for a foundation course should ideally be in the age range 17 - 22 i.e. recently completed high school education.

Study plan: Student should present a logical study plan, e.g. English language - Foundation Program (Business); Degree in Information Technology; Job in I.T. Sector in home country. the visa success rates for students applying for a 2-4 year program of studies are much higher than for the students applying only for an English Language course.
