Legal immigration is great. The problem with cities not enforcing immigration policy is that it can lead to:

• Increased crime
  • People entering the country aren’t background checked and processed
• Increased underpaid or unpaid workers in poor working conditions
  • They aren’t legal citizens, so unfortunately don’t have much in the way of legal rights
• Increased strain on social programs
  • This lowers resource availability for the legal citizens that depend on those programs and pay taxes to fund them.
