Timeline for entering USA for visitors

[mgirish]

Hi All,

My parents will be going for an interview in next couple of weeks to obtain visitor's visa to USA. Does anybody know the timeline for entering the United States once the visa is approved? I guess I want to know is there a timeline such as 3 months/6months etc during which you have to enter USA?

Thanks in advance for any input that you can provide,

No such limit. They can enter anytime before the visa expires.
And their stay duration will be determined at the port of entry.
