Usually, the US Preclearance at Dublin Airport opens at 7am... the reason we say 'usually' is that the United States Customs and Border Protection Officers can delay or close Preclearance at any time if they deem it to be necessary for security reasons... regardless of your flight.

US Preclearance at Dublin Airport can take anywhere from 5 minutes to 2 hours. But in most cases, you are looking at a 20-40 minutes wait time.
