Before the end of the year, presidents often consider grants of pardon and amnesty. This year, Pres. Obama should grant amnesty to the 11 million undocumented immigrants in America, excluding those guilty of heinous crimes like murder, rape, armed robbery and child abuse.

Undocumented immigrants work hard, make great sacrifices, save their earnings and rely primarily on themselves and their personal networks to survive in this country.

They take jobs commonly discarded by average Americans due to low pay and low social status.

From washing dishes to parking cars, from cleaning toilets to changing diapers (both for children and some elderly), from picking tomatoes to mowing lawns, immigrants toil daily in these so-called dirty jobs.
