Help send my mom to Mexico

My mama’s grandmother (my great grandmother) died yesterday of multiple strokes and my mom hasn’t seen her in over 10 years since she is in Mexico and my mother only recently was approved of her green card. We would love to send her so she can attend the funeral and be with her own grieving mother. We are low on money right now due to bills and loans but would really wish to have my mom see her grandma. Please help my mom say goodbye to her abuela one last time. Anything helps. Thank you for taking the time to read this.
