Yes, I am. In the UK it is a 5 year medical degree with 1 year internship. I practiced 6 further years (Emergency Medicine, Intensive Care) before I went into tech.
Edit: I should add I am certainly not licensed to practice in the US, though our training is roughly equivalent. You can read more about the differences and transfer process here: https://www.bma.org.uk/advice/career/going-abroad/working-abroad/usa
