Whether we Brexit or not, the UK's booming digital sector needs access to the worlds best digital talent. We need to develop and train large numbers of people to take up an abundance of opportunities in coding, product dev, analytics, marketing and sales. We also need to be able to welcome talent from around the world to continue to grow the sector and boost the UK economy. Immigration is a political issue if people enter the market and drive down wages for incumbents. Can't see how that can happen in a tech environment where supply and demand are the forces for change.
