Help my mom get her papers

Hey everyone. For quite some time now my mom has been trying to get her papers fixed. She moved to the states legally from Venezuela when she was around 25, leaving an abusive relationship, with her two small children. She then met my dad and had my older sister. Her visa expired but she remained in the states, as her family was now here. She's worked her whole life since being here, from housekeeping to taking care of children. Even now being an older woman, she continues to work. She has been trying to save and come up with the funds she needs, but with so much on my family's plate and her small income, this has been hard and unattainable. My older brother was deported 7 years ago and as my mom gets older she wishes nothing more than to be able to see him again, along with her dad and sister in Colombia, and still have the ability to come back to her children and husband in the states. While my mom has been in the states, she has suffered the loss of her mother and her brother and wasn't able to attend either funeral in Venezuela and Colombia. She didn't get to have her final goodbyes or be with other family. She's slowly paid an upwards amount of 5k in legal fees with still no results because there is so much more to do. Her biggest issue with trying to get her papers is locating documents of her legal entry from Venezuela. Because of the current political climate in Venezuela, this has been hard and expensive. Asking for help is difficult and feels a little embarrassing for some of us. I'm giving mine and my family's vulnerability, and asking for any donations in this time, because my mom has been in this process for 20+ years.  Anything is appreciated! Even just reposting this is also helpful. Thank you <3
