Earlier quoted context omitted.
Going to a country for work on a tourist visa (waiver) and without a working permit is ridiculous on top of staying longer than the usually allowed 90 days in any sequence of 180 consecutive days. Do not put yourself in a position for a foreign government to put you in detention and "hope for the best".
Agreed. But I care a lot more about what my government does to people who break the rules than I care about people breaking minor rules.
AFAIK, US usually resolves that with courts (in this case Immigration Court). That requires a court date which is not as quick to come by.
The way to improve the situation for the future is to introduce changes to the law to allow voluntary deportation for anyone who's not a wanted criminal — but the laws are what they are, and I wouldn't want immigration clerks to have the full power.
