Here are some questions on immigration for the Democratic Presidential candidates:
1) Should there be any limits on the number of people who can come live in the U.S. each year?
2) Should there be any limits on the number of people who can become American citizens each year?
3) If you think there should be limits under 1) or 2), how should those limits be determined?
4) If there are limits under 1), and people come to live in the U.S. in ways that evade those limits, what should happen to them? Should they be allowed to stay here?
