What happens if an American gets denied entry from Uruguay

[BarryBloomWwf]

Do they get deported to Uruguay or the USA?

If they are refused entry it will be in Uruguay if they are in Uruguay. I read a few stories of Americans getting rejected but it seems like they got a warning before leaving Argentina that they might have a problem. This seems to be people that repeatedly are overstaying or paid many overstay fees.

I haven't heard of any Americans that are getting rejected from flying from the USA. I'm not sure what they would do in that case since flights back to the USA aren't until evening.
