My mother-in-law has visited us in the USA twice before from the PRC. I've heard that it's easier to arrange a visit again. Is there a way to arrange for a visit where she won't have to go through an interview (which itself would require her to travel) or me to generate reams of paperwork including bank statements and whatnot?
I'm a 3rd (or more) generation US citizen. My wife has recently become a naturalized citizen. Since her last visit, Mother-in-law has been widowed, so she would be traveling alone. She's also quite elderly.
What paperwork do I need to look for? Any recent advice from someone in the same situation?
