Japan been doing it for years. They find you overstay your visa and you are deported. Because illegal....It’s the norm with proper countries. Excepting US under liberal policies. A visa is merely a license allowing you to stay in a foreign country. No “license” and you are or should be gone.
(Try flying into Singapore without a RETURN ticket and see what happens. They actually ask you for this when you enter the country)
Probably also surreptitiously taking a DNA sample for their “research”.
The Ninth Circuit judges will step in and tell China that this policy must stop.
“China Will Soon Collect and Store Foreigners’ Fingerprints upon Entry”
BFD, they already have the fingerprints of everyone who works in the federal government and contractors that require a security clearance, remember, the OPM data breach that the media couldn’t be bothered with — Oh and by the way, odunga never lifted a finger about that, the big F’n $ussy!!!
Here again the commies gave odunga and the American left something to get outraged about, but they would have to side with the American people.
They’re probably doing this to crosscheck with 22,000,000 U.S. governmental employee personnel files they hacked a couple of years ago.
