If the student is holding the conditional offer for Ireland can he apply for the visa?

A conditional letter is an acceptance letter that outlines certain conditions that have to be met to get unconditional admission for a study visa. For instance, you may need to provide the proof of English language proficiency. In simplest terms, you will need to remove all conditions before getting a study visa to cover the duration of your program. The government usually avoids granting a study visa to the students who fail to satisfy the conditions.
