Deportation proposal could cost $585 million

Here are details about who may eligible to apply to stay in the United States under the Obama administration's new immigration plan, how the process may work and what it may cost.

— Illegal immigrants who can prove they arrived in the United States before their 16th birthday; are younger than 30 years old; have graduated from high school or are in school or served in the military; do not have a criminal record or otherwise pose a security threat are eligible to apply.

— Those people not already in deportation proceedings can send a form, "Request for Deferred Action for Childhood Arrivals," to U.S. Citizenship and Immigration Services starting Aug. 15. They will apply for a work permit at the time and likely will have to pay $465 in paperwork fees.

— It could take several months from the time the application is submitted until a final decision is made.

— U.S. Citizenship and Immigration Services estimates that about 1.04 million people will apply to stay in the country and obtain a work permit in the first year and that 890,000 could be immediately eligible.

— DHS Secretary Janet Napolitano has said people waiting for their applications to be processed generally would not be detained by immigration authorities.

— USCIS estimates that it could collect more than $484 million in paperwork fees. Cost estimates for the program range from $467 million to $585 million for the first two years of the program. That means the cost to the government could range from a gain of $16 million to a loss of more than $101 million.

— The government also estimated it could need to hire more than 1,400 new employees and contractors to fully implement the program.
