One of the bigger concerns for some companies is about any international developer is intellectual property (rather than talent). 99% of them will not do this, but if someone does take your codebase and launches a copycat site, there is literally nothing you can do. No common court system where you could go after them. Not saying this has really stopped us (we still work with the occasional talented international dev that was referred) but all other things more or less equal, this can have a slight chilling effect on hiring.
