Before joining my current job, I was interviewing for a position at one of Toyota's R&D spin-offs. While they made a stellar job at selling the company (and ensuring all immigration support, from language classes and professional assistance for the process of moving and finding a home), in the end I opted for a lower-risk, lower-friction option because I have a pre-teen daughter and moving countries is a bit stressful, especially crossing such a cultural chasm.

It's still something I would contemplate at a later stage - I actually enjoy jumping cultures.
