Re: B1/B2 One Month Single Entry Visa with Annotation
Quoting Mr. Knowitall
Is the visa marked "R" (restricted)? If so, an attempt to enter significantly before the commencement of the specified event is more likely to be problematic.
It says Issue Date 8/29
Expiration Date 10/9
That means that the visa is good now...it was good as of 8/29. There is absolutely no problem with him going a week or so early.
