At a company I used to work for, there was an Indian DBA I worked with remotely who was on the East Coast. One time when I tried to contact him, he got back to me saying his schedule was different as he was now in Australia. Turns out there was some issue with his Visa, but no worries, apparently the company had an office in Australia where they would send these guys and Australia was happy to take them.
My Aunt and Uncle had a Russian student living with them. When she finished college, her visa expired and she had to go back to Russia. She couldn’t get back in the US on a work permit for years. She went through years and years of hassle to get back in.
But for some reason, we let in a bunch of illegal and undeucated people in through the Southern border with no issues?
