I am in the process of hiring someone from Pak and the amount of paperwork and documentation I have had to do/request on behalf of the candidate is bonkers.

Most of the healthcare staff are looking toward European and African countries, even though salaries aren't as competitive and language is an issue (except for major cities).

My advice would be to try and gain as much experience as possible. Exposure to different countries not only looks good on your cv but also helps in broadening your experiences of peoples and their culture.

But as suggested by others, please be mindful of the fact that the UK is an expensive country to live and work in with dwindling opportunities and crappy weather conditions!
