While on the campaign trail, Donald Trump made it clear that he wanted to deport illegal immigrants. His stance on high-skilled immigration, on the other hand, was more opaque. The H-1B visa is the most common pathway for high-skilled foreigners to work in the US. Trump called it "very, very bad for workers" on the campaign trail and, after being elected, pledged to investigate visa programs that were abused. However, he also admitted that he's hired H-1B workers for his own businesses.

Uncertainty over what will happen under Trump has some foreign engineers thinking twice about working for a startup.

Some of the world's richest countries are very poorly served with mobile Internet. The US, UK, and Germany are still lagging behind developing nations when it comes to 4G access and download speeds. A report by consultancy OpenSignal found that American users have to put up with an average speed of just 13 Megabytes per second. That's the 69th slowest in the world, and way behind countries such as Ecuador (25 Mbps), China and Kazakhstan (both 22 Mbps). World leader Singapore boasts 46 Mbps. And the global average stands at 17.4.

While the US ranks poorly in speed, it's doing much better in terms of access. A typical user in the US can get onto a 4G network 81% of the time. That puts the US in 10th spot in the global ranking. The UK, by contrast, ranks just 54th in the world in terms of 4G availability. A typical user in Britain can only access 4G 58% of the time, behind Albania, Panama and Peru. Speed in the UK isn't all that great either, although with 21 Mbps it is still doing better than the US.
