What we know about RAICES, the group raising money to reunite separated immigrant families

(CNN)In the discussion about immigrant kids separated from their parents at the US-Mexico border, one name comes up often these days: RAICES.

The Texas nonprofit is the intended recipient of several online fundraisers that's collecting money to help reunite the families, including one that has already raised more than $20 million.
Here's what we know about the organization:

What does it do?

    RAICES, pronounced ruh-EE-ces, is an acronym for the Refugee and Immigrant Center for Education and Legal Services. It offers free and low-cost legal services to immigrants and refugees.
    It has 130 employees: a mix of attorneys, legal assistants and support staff who consult, represent and advocate for clients, according to its website.
    The organization also works to educate communities and lend social support.
    "Our advocacy and commitment to change are driven by the clients and families we serve every day ... in an immigration system that breaks apart families and leaves millions without pathways to legal status," the group says.

    What are some of the services it offers?

    RAICES offers consultations for immigrants filling out residency or citizenship applications. It also offers legal services to asylum-seekers eligible for relief, victims of crime or Texas residents at risk of deportation.
    For those in the US with DACA status, RAICES can help with renewals. Its offices also serve Temporary Protective Status recipients.
    The organization recently launched the Family Reunification Project with the Texas Civil Rights Project to identify families separated at the border.
    Since June 1, officials with the group say they've received the names of 184 people separated from their children in court in McAllen, Texas.
    Last month, it created a "National Families Together Hotline" -- 1-800-ESTAMOS. Executive director Jonathan Ryan told CNN the group has been calling the families of detained people, as well as service providers and detention centers, in its work to reunify families. But there are still obstacles to overcome, like getting rejected from paying immigrants' bonds, he said.
    "These are examples of little hurdles that we get that makes helping so many people quickly a really difficult logistic," he told CNN.

    How many people does it serve?

    Since its founding in 1986, RAICES has become the largest immigration legal provider in the state, according to its website.
    In 2017, RAICES staff say they have closed 51,000 cases that were free for their clients, per the website.
    It has offices in several cities in Texas, including Austin, Dallas and Houston.
