The Obama administration said Friday it will begin charging $465 this month for temporary work permits for many young illegal immigrants, as it laid out details of one its signature new policies on immigration.

U.S. Citizenship and Immigration Services will begin accepting applications Aug. 15 for the permits that are subject to renewal for two years. It will consider a limited number of fee exemptions but expects costs to be shouldered by applicants, not taxpayers.

Under the program, which President Barack Obama announced in June, immigrants must have arrived in the U.S. before their 16th birthday, be 30 or younger, lived in the U.S. at least five years and be in school, graduated or served in the military.

They are ineligible if convicted of a felony, three misdemeanors or one "significant" misdemeanor.

Significant misdemeanors, as defined by Homeland Security, are any offenses that result in more than 90 days in jail, and some offenses regardless of the sentence, including domestic violence, burglary and gun and drug crimes.
