[IWantOut] 34M Bangladesh->UK

Hello, I'm a Banker from Bangladesh with a wife and a kid. I have experience in banking technologies like Robotic Process Automation and Document Management.

I want to migrate to UK (preferably) or Europe. People have advised me to look for jobs that will sponsor visa for me. How and where do I start looking for these types of jobs? Is the idea to migrate to UK/Europe good or bad?
