Ask HN: Where to emigrate to as a data scientist?

I am a data scientist living in Edinburgh, UK. I want to experience living abroad and I'm utterly bored of my current job where I am spend most of my time increasing the efficiency of our ad-serving platform. I have a PhD and two years experience industry experience. Where do people have positive experiences emigrating to? USA seems ideal (esp. NY, California) although it is extremely difficult to obtain a visa/residency. Canada is comparatively easy for British people (working holiday visa and the ability to gain residency), although it's hard to understand the strengths of the job market there in comparison to Edinburgh/London. I'm open to locations in Asia in particular Hong Kong or Singapore. Ideally I would move first, take a 1-3 month break while searching for a job and then commence employment. Is this feasible in those (or any) job markets? How does the ML/DS industry compare in somewhere like Hong Kong vs. the gold standard of Silicon Valley?
