Years ago, my Dad had a yard sale and three Chinese guys stole items from him. I don’t know their status, but I wouldn’t be surprised if they were illegal, and from Philly.
I refuse to have garage sales anymore.
We just bag the stuff up and give it to charity and let them sort it out.
What happens with garage sales is that a whole bunch of illegals show up all at once, overwhelm the sale, distract the people giving it, and when they leave, all items of value have been stolen.
