I'm Filipino on an F1 Student Visa from the US. I'm flying back to the US from Germany. I have a 4 hour layover in Dublin on my flight back to Chicago. My flight arrives in Terminal 2 and I depart for Chicago also in Terminal 2 (Aer Lingus flight, on a single-ticket with my luggage checked through to my final destination). I know I have to go through U.S. Customs and Border Pre-Clearance. On my way to pre-clearance, will I have to go through Irish Immigration?
