My wife's family wants to get visas to come visit us (from Peru). Her parents I am not worried about at all as they both have career jobs, have a house, bunch of property, etc. However her brother only works for his dad and lives at their house. He had brain surgery last year to remove a tumor and has occasional seizures when he gets lax on his medication. My wife's mom does not want to leave him alone as she has to be there for him although he is generally healthy. Does this factor in at all in the application process? Obviously he doesn't have a case for "strong ties to the country". My wife got rejected for visitor visas twice before our K1, so they are worried about it. Not sure if any other visas would qualify if they wanted to get him looked at by a doctor here (want to see if there is any kind of other medication he could take). But their main goal is just to visit us so don't want to come across as untruthful to the embassy. Any advice is appreciated.
