And if they don't like your answers, they can detain you without charge indefinitely and then deport you -- and not necessarily to your home country.
It's a bad idea to come to the US -- for any reason -- at this time.
N.B.: I say that as an American living in the US. What's more, my father was an immigrant (who never became a citizen) and my mother's parents were also immigrants. As such, were it not for immigration, I would not exist as my parents met here in the US. Please don't come here. It breaks my heart to say it, but it isn't safe for you.
To clarify, my admonition not to visit the US wasn't a warning from a xenophobe promising harm to foreigners.
Rather it was an earnest concern for the health and well-being of fellow humans given the harsh, punitive and cruel tactics being used on people by my government.
If and when we stop treating visitors like criminals, I will once again heartily recommend that folks come and visit the US. It's an amazing place with all sorts of fabulous places, things and people. And despite the loudest and nastiest among us, most Americans are kind and decent people.
