I'm a US citizen, my wife got her 10 year greencard through marriage 7 months ago.
We want her mother, to visit us from Turkey. Her mother owns a house in Turkey, she is retired. She's coming only to visit us. We don't have kids either so no babysitting.
Is there anything we can do to increase her chances of approval ?
Her only child is my wife and she isn't married either. But she had cancer a few years back and gets checkups from her doctor. She also has a sister who she takes care of from time to time.
