I wanna know the possibilities of inviting my grandma from Philippines. She is 79 yrs old. I am 16 yrs old and working part time. My Mom only work part time too and we are considered in low income family. We cannot go visit her not until the next two yrs and we want to see and be with her. I am pkanning to invite her for 2 to 3 months. She never travelled elsewhere her entire life and she was retired from many years.
