"The first thing you get from us is normally just the admit letter. You will not get the BecomingIrish binder and the I-20 info until you confirm your seat. So the first thing you want to do is confirm your seat. That allows us to change some statuses in the University systems and gets the process rolling.
If you filled out the "roof of Financial Resources" form when you first submitted the application, then when you confirm we will send you both the BecomingIrish binder and the I20 info. (please note that everything in the binder is available on the website - it's exactly the same)
However, if you confirm your seat but we don't have your Proof of Financial Resources info, then we can only send you the binder. We must have confirmation of your seat AND the Proof of Financial Resources information before we can send your file to ISSA. They are the ones who process and handle your I20 process.
I hope that clarifies - please let me know if it does not. "
