U.S. Debit Card To Verify Snapcash

I'm currently living in E.U. , but I often travel to U.S. and I also have a U.S. mobile phone number so I'd like to use the snapcash feature on snapchat ; How could a non U.S. Citizen get to hold a regular debit card in order to send and recieve payments via snaps??

Anyone offering some advises??
