1. During the Obama era, it was easy to apply for a green card. In the last year of Obama's administration, 1.2 million people got green cards.

2. During Obama's administration, the immigration policy of the United States gradually tends to be conservative, and even has a certain populist tendency, which cannot stop the great changes that Trump will bring to the immigration policy of the United States after taking office.
