A detail to ponder

Hi, readers. Yes, I am actually posting something that isn’t about food.

I have a little question and I would love everyone’s opinion. In recent discussions, I have become increasingly aware that when I am talking about the country I’m from, I refer to it – without fail – as ‘the United States.’ I have ever since we got here – I remember clearly asking in my German class how to correctly decline ‘I come from the United States.’

How do you refer to my (and possibly – but not necessarily – your) home country when mentioning it in conversation? No right or wrong here – just my own curiosity.
