"We've issued 40 million green cards since 1970, which means the permanent residency and a path to citizenship for many, many people. But we will not allow our generosity to be abused by those who would break our laws, defy our rules, violate our borders, break into our country illegally. We won't allow it.

Mass, uncontrolled immigration is especially unfair to the many wonderful, law-abiding immigrants already living here who followed the rules and waited their turn. Some have been waiting for many years. Some have been waiting for a long time. They've done everything perfectly. And they're going to come in. At some point, they're going to come in. In many cases, very soon. We need them to come in, because we have companies coming into our country; they need workers. But they have to come in on a merit basis, and they will come in on a merit basis."
