If I was hiring developers, I wouldn't care much where they come from - if someone from Sweden wants to come to Portugal, I wouldn't stop them, but on the other hand I wouldn't give them extra assistance/benefits just because they're relocating (assuming that (1) there was enough local talent available, and (2) the company was a startup, not an established company with loads of cash). On the other hand, if I was hiring developers, I would stick to the contract.
