Yes, she has 1-year valid, muti-entry visa. my concern is that she applied it for Business and Travel, not for visiting me, although both Business and Visiting visa are B1/B2. I understand if she comes for Business and Traveling within 1-year, she definitely does not need new visa. I am not sure if she need new visa if she comes back to visit me within 1-year.
Thanks
