When debating current issues, it’s helpful to avoid inaccurate depictions of past policy, especially on immigration, in which both opponents and advocates of President Donald Trump’s policies have views based on not altogether accurate renditions of the past.

Many opponents of Trump’s policies seem to believe the president wants to cut off legal immigration altogether: shut America’s gates. But in recent times, around 800,000 people have taken the oath to become American citizens. In addition, about 1 million people have been granted green cards each year, making them eligible for citizenship. That’s not a closed gate.
