Tesco needs my passport but I sent it to Student Finance...

So I sent my passport recently to student finance (since I am originally from Netherlands so I had to) and I got invited to a Tesco Interview and they are asking me to bring proof that im legally allowed to work and they gave me a list of things that I could bring. Only problem is my passport is the only thing that meets the requirement but I sent it to student Finance. I do have a copy of my passport but they want the original passport.

What can I do?
