So many, really. It seems to depend on the agent. I’ve passed through US customs and not gotten stamped. Israel famously does not. They’ll give you a small slip with your details on it. I was told that an Israeli stamp on your passport would automatically bar you from entry in many Arab states so they came up with another system Also pretty much anytime I have entered the UK via the global entry lanes I never got stamped.
