My son has working permit by dream act. Was attack for 5 kids and make police report can he apply for permanent recident

Your son may be able to apply for a U visa. More information is needed about the crime and investigation to determine his eligibility. While a U visa does confer permanent residence in your son, it may give him a path to permanent resident. I encourage you and your son to speak to an attorney. In the interim, you can read more about the U visa at http://myattorneyusa.com/u-nonimmigrant-status-u-visa.
