They call it a common gesture of courtesy to inform people that your home would offer itself to those fleeing some kind of devastation (oppressive regimes, abuse, earthquakes, etc.). However, most people don’t end up in that kind of humanitarian role. What’s the closest you have come?
When the Ukraine war kicked off I called the Ukrainian embassy in my country and let them know that my upstairs bedrooms were empty, and that if they could get the people to the US, I could house some. Then I called all of my representatives and senators and asked for refugee status for Ukrainian citizens.
In the end because of political fuckery I didn’t end up hosting any Ukrainians, but my coworker who’s from Ukraine was able to get her family over here.
