> I thought part of the job of immigration officers is to screen travelers for ability to sustain their trip? Visa waiver does not mean you are entitled to enter. Correct, but in practice the level of scrutiny depends on where you're from, and which country you're entering. From what I've heard, people from rich Western countries, like the US or Canada, are generally allowed in with only perfunctory questioning, especially in countries where the immigration officers are known to be more relaxed. So an unprepared American is still likely to get into the EU, but a Colombian would probably be questioned more, despite being in the same legal category as a US citizen.
