B2 visa 10-year multiples entry questions

Hi again, 

Now that B2 get 10 years multiple entries,  I would like to help grandparents to apply for it, have the visa on hand, then decide when to actually travel to the US. The purpose would be tourism plus visit my family. I have a stupid question,
- if the B2 got approved, is there a timeline that they must travel before that date ? can they travel anytime within the approved 10 years ?
- if they decide to travel 2-3 years later (after the B2 visa is approved), which make the original supporting documents out of date, for examples, travel plan, my legal status in the US, my employment etc, would that put a risk at the port of entry, that they maybe rejected ?

I know most people doesn't have experience with the new 10 year B2 visa policy yet, but still like to hear your opinion. Thanks ahead for sharing

• 我覺得沒問題。入關的時候解釋清楚了為啥申請了簽證當時沒來就可以了。不過如果英文交流費勁的話，不建議這麽幹，什麽時候真想來再申請多 -迷糊桃紙- ♀ (0 bytes) () 12/08/2014 postreply 07:08:16
