The Security Through Regularized Immigration and a Vibrant Economy Act of 2007 or STRIVE Act of 2007 is proposed United States legislation designed to address the problem of illegal immigration, introduced into the United States House of Representatives (H.R. 1645). Its supporters claim it would toughen border security, increase enforcement of and criminal penalties for illegal immigration, and establish an employment verification system to identify illegal aliens working in the United States. It would also establish new programs for both illegal aliens and new immigrant workers to achieve legal citizenship. Critics allege that the bill would turn law enforcement agencies into social welfare agencies as it would not allow CBP to detain illegal immigrants that are eligible for Z-visas and would grant amnesty to millions of illegal aliens with very few restrictions.
