Send Mom to her Home Town

As many of y'all may know, my mom has stage four colon cancer. She is a very strong and selfless woman. She made sure we had everything we ever needed. Especially before the things she wanted. I'm trying to send my mom who has not been to her Home Country in 20 years. She deserves to go home and visit her parents while she has gotten better while fighting her cancer. She has been married to my father, who is a disabled veteran for 28 years. Who also has some health challenges. It would be amazing and I would greatly appreciate it. If y'all would help me allow mom to make it back to Germany to visit her remaining family. Thank you for your help!
