B2 Visa Extension arya2004-08-16 20:25:41

I would like to extend my parents' B2 visa for another 6 months. I only bought one-way tickets for their coming. I am just wondering if it is necessary or very important to provide a copy of returning air ticket to visa officer for their extension. What else should I provide to get the extension approved?


Thanks in advance!
