Hi! You have a couple of options. The first option is to go to the FlashSeats website to see what other options they provide for event entry. Usually, they have another option which allows you to attach the tickets to a debit/credit card. The next option would be to download the app from the U.S. store when you are in the states. The only trouble with this option is you generally need to create a new Apple ID or Google account to use on the US Stores. The final option would be to collect the tickets from the venue Box Office on the day of the show.
