A very dear friend has been offered a postdoc position in the US. He has been there a few times as his girlfriend is American. He's now been refused entry in the US because he's been there too many times visiting her, so he must be seeking to work illegally. Obviously!
Border control were not interested in seeing his job offer, or other documents, they just read his WhatsApp messages...

It's easy to pontificate on how people you've never seen and don't really care about in a far away land should rise up against their authoritarian regime... then you create the same regime in your own country which you viciously say you want to make great...
