If someone has the same dilemma in 2017, the answer is: if you are very good at something, it's really easy to find a job in the UK, regardless of which country you're coming from (unless you're from North Korea ). If you can provide extreme value with your skills, then get in touch with many companies and show them what you can do, and they will do whatever it takes to employ you, and to resolve the paperwork. Highly skilled people are extremely sought for, and you'll earn quite good money if you're among the top 1% of the people in your trade. For example, my partner (for 3 years now) is from Kuala Lumpur (Malaysia), and she's an extremely talented Java developer. She's literally been hunted down by UK recruitment agencies about 4 years ago, and she's earning  £61K/year, which is a fair wage for a Java developer in London (leaving her with around £3,600 net/month, src: tax calculator). Make sure you've got the skills, and there are plenty of opportunities for anyone, from anywhere Hope it helps.

It maybe easy to locate a job here but very rare to earn £3,600 per month, I'm a graduate engineer with 5 years experience and still only making 22k so £1,520 net take home per month after tax according to http://after-tax.co.uk/?income=22000

Here is a better, more visual alternative to the tax calculator above: Icome Tax or a more simple one After Tax. I hope it helps

It's been five months or so after I transferred to UK under the T2 visa and sponsored by my company.
This was one of my biggest decision I have made in my life to relocate in a foreign land on my own. Currently staying in Nottingham, going down to London occasionally for business trips.
If you are happen to be around this area happy to go for a meetup.
