Help Lien's Family Visit Dying Aunt in Vietnam

Hi, my name is Lien M. Schuller. My aunt, Yen Tran in Vietnam, is dying. My mother, who is her younger sister, Lien T. Schuller, and her granddaughter, Shayla, are here in the US. I would like to send my mom, Shayla, and my dad, a Vietnam Vet, to Vietnam ASAP to make a dream come true. My mother cannot travel alone due to her health and memory issues. Shayla is inexperienced with traveling abroad. My father would be the perfect escort for them. Any help would be greatly appreciated. This will most likely be the last time my mom will be able to travel to Vietnam due to her health. Thank you so much for your support and help.
