I am moving to Korea soon and want to know how safe it really is for foreigners?

Korea is consistently ranked one of the safest countries in the world, and as a foreigner you can generally walk around late at night and use public transport safely even after midnight. The main things to watch are occasional pickpocketing in crowded tourist spots, scams that target foreigners (fake rental listings, phishing texts, fake job offers), and traffic where scooters sometimes ride on sidewalks, so look both ways. Save 112 for police and 119 for medical emergencies, both of which connect you to interpreters, and keep your ARC on you.
