The biggest obstacle is that unless you have a European passport at the time, you can’t legally work. You might pick up under-the-table small jobs. But if your boss stiffs you, what are you going to do? Tell the authorities, who will then proceed to deport you for illegally working without a pre-approved permit (work visa), enrollment in obligatory tax withholding, etc.? You’ll also need a new passport after that.

I’m British, so part of the European Union so I don’t think that applies to me? But thank-you.
