I plan to sponsor my parents in Jan 2019. My father is a disabled person, he is paralyzed from waist down and has been like this since 1984. He did not any other issue, worked throughout his life, retired as a very high government official in Bangladesh. He does not have any other health issue so far. Just wondering if I want to sponsor him whether there will be any issue in terms of his health since he is disabled. I could not really find any information about this in the web about this.
