The group noted that there are an estimated 5,081,000 “Latino-eligible LPR” that could naturalize and vote in the coming election.

“These LPRs can help elect candidates who will fight for the well-being of our families and communities,” Mi Familia Vota added.

The citizenship workshop drives are scheduled to take place Saturday.
Even LPR's who commit certain levels of crime can be deported. Once they are citizens, though, it is much harder to do that.

"A primary purpose of U.S. immigration laws is to control the number and type of non-citizens who can be in the country. Among other things, these laws outline conduct that can disqualify non-citizens from getting permission to enter or remain in the U.S.

A key mechanism for enforcing the law against non-citizens already in the country is through their deportation. Under the law, one way such actions are justified is when the individual involved has been found to have committed various crimes. This report focuses on what are called "aggravated felonies" -- a single part of these laws. The subject of aggravated felonies is important because it is little understood outside a small community of immigration lawyers, judges and scholars, and yet affects the lives of tens of thousand of non-citizens who have entered the country legally."
