Cứ để nguyên như thế
chính sách nhập cư của Mỹ có lẽ tốt hơn bạn tưởng,
Canada nhập cư nhiều, 400.000 tới 500.000 người/năm, mà những người kỹ năng cao sẽ lại từ Canada qua Mỹ (O-1 visa)
Keep in mind that Canadian immigration policy (chính sách nhập cư) also is U.S. immigration policy. Currently Canada is taking in about 400,000 people a year, with plans to raise that to 500,000. At the same time, the U.S. is doing little to boost high-skilled immigration (nhập cư tay nghề cao). But Canada is serving as a kind of farm system for the U.S. The very best Canadian arrivals — or their children — have the best chance of getting into the United States, if only through O-1 visas.
So if the quantity of Canadian immigration is going up, the quality of U.S. immigration is going up too, through Canada in this case. Call it cherry-picking if you like.
Not surprisingly, neither side in the immigration debate wants to scream this loudly from the rooftops (hét to điều này từ mái nhà). The pro-immigration side wants to present the status quo as dire (tàn khốc). The immigration-skeptical (hoài nghi về nhập cư) side does not want to stress that there are perfectly good ways of screening for immigrant quality, some of which already are in place.
