My mom (81 yrs old) will visit us as visitor. She came to USA before back to 1996.
Here are details of her visa history:
Her first visit on March 1996, she got 6 months stay period when she entered the US port, then she did twice extension (6 months per extension) then, she left USA on July 1997 before the extension visa expired.
In 1999, 2008 and 2010, she had tried to get visitor visa and all of them had been rejected.
Finally on May 2012, she got visitor visa. Because new visa good for one year period before expired, so she will enter the US on April 2013.
According all of the facts, does she need Round Trip ticket to enter the US with a Visitor Visa? I'll back to my country and go with her to enter US. I am green card holder (just got it). How long can she stay in US for this time?
