After 23 years separated, Elena Daz, with tears flowing down her face, finally embraced her 74-year-old mother, Catalina Daz.

The last time the two saw each other was just before the daughter embarked on a journey from Mexico to the U.S. for a better life. The emotional toll of not being able to visit her mother weighed heavily on Elena and her family.

Its sad. Its sad because there is so much distance. Gods timing is perfect, she said of the reunion.

Dazs mother was part of a group of about 10 parents who were reunited with their families with the assistance of nonprofits Races del Sur and Esperanza en la Frontera. Races del Sur, which means roots of the south, assists Mexican parents who have adult children in the U.S. in obtaining visas to visit their families, regardless of the childrens immigration status.

To obtain a tourist visa through the program, the parent must be at least 60 years of age, have no prior deportations with false documents and have a valid passport.

Elena Daz said she learned about the program through a post on Facebook, where she saw a video about another family being reunited. She immediately sought to learn more about the group to see if it was a possibility for her mother to qualify.

Daz said she was surprised when her application was accepted, and after about 14 months of waiting, her mothers visa was approved for 10 years.

Its beautiful because you dont expect that they will be able to help you. And when you are told yes in reality whatever you pay, its nothing its all worth it to see your family, especially when its a mother and father who are the pillars of a family, Daz said.

The Nov. 18 reunion of the Dazes was part of the third annual that Esperanza en la Frontera and Races del Sur held together. The groups say they have reunited more than 30 parents with their adult children.

Alma Mendoza, director of Esperanza en la Frontera, helped host the event held at La Oaxaquea, a Mexican food restaurant in north Phoenix. The group, whose name means hope at the border, travels to and from the U.S.-Mexico border to provide basic needs to migrants, including clothes, shoes and food.

According to Mendoza, the majority of applications for visas through Races del Sur are approved. Families are responsible for covering the cost of travel and application fees but assistance is offered if the family is experiencing financial hardship.

I think that the longing to see ones parents is a longing that every son or daughter has. Many of them are unable to leave the country, which is the reason we work together to reunite these families, Mendoza said.

Elena Dazs mother made the more than 1,500-mile trip to Phoenix from Cuernavaca, Mexico, by plane to see her great-grandchildren for the first time. Elena was just 20 years old when she arrived in the U.S. now shes 43. Through phone calls and video chats, she stayed in close contact with her mother, but it didnt make up for not being able to see each other in person.

Catalina Daz will stay for a month and a half and will visit her family members for the holidays through the new year. She said she plans to visit her family as often as she can with her new visa: God willing, I will return.
