If you don't mind me asking, why would you want to move to London? Are you looking for more opportunities, or a better salary?
As someone who's living and working in HK as a SWE, you can definitely get a much better salary here in HK if you're fairly experienced. Carreer opportunities are limited tho, because none of the FAANG companies have engineering offices here.
Basically I just want to go somewhere to start fresh... not really career prospect/salary motivated.
London looks a good option to me because its english-speaking, I have relatives living there, I can work there visa-free (now its complicated due to brexit), and I love english football haha.
