I have never needed a visa when doing a turn, and Canada is the only country I'm aware of that requires us to do the customs/immigration dance when not leaving the airport (only if your ground time is over 90 minutes).
When we return to the US, we still have to do customs/immigration (unless we're returning from a country where passengers were able to clear into the US there - such as Canada).
Some countries (France, for example) prefer US crews to have visas even when they're not required for US passengers - as a courtesy to their government, I was told.
Stuff like this will vary according to the country, and to their relationship with the crew's home country.
