Hi,
Welcome to the forum firstly!
Secondly, make sure you do your due diligence very very well. The UK is in a weird place currently and perhaps over the next 2/5/10+ years given the absolute mess that is Brexit. Immigration is a very hot debate right now and given the uncertainty in the economy, there's more examples of companies announcing layoffs, freezing in hiring and all the political level talk of 'wanting to attract professionals' to come here.
You've not mentioned which industry you are in now, or the one you may want to switch to. Again, the political talk mentions the UK wants Doctors, Engineers, Scientists, highly educated and specialist professions etc, so if you are in one like that or want to go into one of those, then in a few years there may be more actual demand. To give you more of a picture, just a couple of weeks ago, a relative of mine who has never been out of India came over for an 'exploratory' visit to see if he should move his family over. He and his wife are medical professionals (Surgeon & Dentist respectively) and are evaluating... but he's mentioned he's put the UK as the last resort currently.
There'll be others who are in the same boat who will have the UK as their first choice so I'd suggest you come here a few times, get a real view and experience of the UK to see if you really wish to move here permanently. You won't get here with just your wits unfortunately, you'll need more and you'll need to choose wisely. The vast majority of members here will vote for coming to the UK, I'd suggest keeping your options open and looking at other countries as well at the very least.
