Border Angels, along with its more than 2000 volunteers[2] serves San Diego County's immigrant population through various migrant outreach programs such as day laborer outreach and legal assistance, and provides life-saving assistance for migrants by placing bottled water in remote mountain and desert border regions of the San Diego and Imperial counties, California.

Morones has said the "spark" that started the Border Angels work was a trip he took with members of a Catholic Church parish in Carlsbad to canyons in northern San Diego County where children, women and families were living in difficult conditions.

Morones' inspirational talk with Mrs. Kennedy came during an encounter at a dinner in remembrance of César Chávez, the late labor leader, civil rights activist, and farm worker.

''[3] Border Angels helps provide job skills, such as hair, skin and beauty care, to women recently deported from the United States to Mexico.

In April 2016, 20 deported women graduated from a hair stylist course supported by Border Angels at the Desayunador Salesiano "Padre Chava" food hall for indigents in Tijuana, B.C., Mexico.

Morones worked with representatives from the Border Patrol agents' union, state legislators, the University of California, San Diego and the Mexican consulate.

A caravan of 25 cars first went to Holtville, California, to the cemetery where many who died crossing the border are buried in simple, often unmarked graves.

Next, Dolores Huerta, co-founder of the United Farm Workers, arranged a meeting at the Placita Olvera in Los Angeles.

Efforts focused on opposition to Border Protection, Anti-terrorism, and Illegal Immigration Control Act of 2005, which passed the U.S. House of Representatives in December 2005 and would have made it a federal crime to assist people in the country without documentation.

2009 – The group traveled from San Diego to Florida and then to Washington, D.C., where they met with human rights organizations on immigration reform.

2010 – The journey began February 2, 2010, in Sasabe, Sonora, Mexico, and continued by caravan through Tucson, Phoenix, and Yuma, as well as Coachella and Calexico.

2011 – The journey began February 2 in Friendship Park with a press conference and vigil, and the next day headed to Tecate, Mexico, for migrant outreach and water drops in the desert on the U.S. side.

The march, February 2–7 began at Tijuana's Monumento de la Playa, at the Pacific Ocean, and ended at Mexicali's Hotel Migrante, a shelter for people deported from the U.S.

Micaela Saucedo, who participated in numerous annual marches, said: "We do this to make people aware that we really need immigration reform in both countries and we don't want more deaths on the border.

"[12] 2012 – The march began at Cesar Chavez Park in San Diego and was in commemoration of the principles of the legendary farm workers' leader.

The activists traveled from Holtville, California, to Yuma, Arizona, Los Angeles, Bakersfield, Stockton, Modesto and Sacramento.

[15] Border Angels was active during the 2014 American immigration crisis, which produced a surge in unaccompanied children from Central America seeking entrance to the United States.

"[10] The undocumented immigrants were flown to California from Texas in an attempt to relieve overcrowded conditions in U.S. Customs and Border Protection housing from an influx of unaccompanied minors.

This however caused issues when a young girl crossed the border and jumped into the arms of her father, resulting in the event being postponed in 2014.

After speeches from Enrique Morones, Congressman Juan Vargas and Tijuana Council Member Martha Leticia Castaneda, the Emergency Door was opened for five families to embrace for up to three minutes.

Border Angels volunteers and activists frequently visit day labor sites around San Diego county such as Home Depot where migrant workers congregate, and distribute food, water, clothing and advice regarding immigration services, legal rights and offer support.

Founder Enrique Morones is a regular guest on TV and radio talk shows to discuss immigration and human rights.

Morones urged humane treatment of immigrants regardless of their documentation and federal policy that would allow many of the undocumented to obtain a path to citizenship or resident status.

[26] Founder Enrique Morones has received several death threats from those who disagree with Border Angels and its stance on undocumented migrants.

Los Angeles City Councilman and former California Assemblyman Gil Cedillo and playwright Josefina López are among those who have voiced strong support.

We are in this together and support each other in our efforts," said Cedillo, a Democrat who successfully sponsored legislation permitting undocumented immigrants to apply for college aid and was honored by the group in 2011.
