Mass Effect Trilogy PS3 Shepard upload?

[Dargan00]

I bought the mass effect trilogy online, not realising It was a US import (I'm from the UK) I'm not all that bothered about DLC, I just want to know if I'll be able to upload my Shepard to the sequels. Does anyone know?

I think the save file formats are the same regardless of the game's region.

Do you have to finish the game to be able to transfer Shepard?
