A tool at the Own The Dream website helps applicants who may be eligible for deferred action figure out whether they are eligible, and if so, can help them figure out what they need to apply.
There’s an instructional video about the tool.
If you recall, deferred action is an administrative change that took place within the U.S. Citizenship and Immigration Services for DREAMers, allowing them to apply for residency and a work permit if they meet with certain requirements.
