America needs immigrants in order to survive
People in the United States are dying faster than they are being born. It will take generations to reverse birthrate trends (if they even can be), and as such immigration is necessary to keep America going.
Anyone who has been offered employment in the United States should be able to come into the country and bring their entire family, so long as they have not been deported in the past or been legitimately convicted of a violent crime elsewhere.
Employers who hire immigrants without the proper documentation should be severely punished — including up to imprisonment — while the immigrant should be given a chance to get the correct documentation and find employment.
