请教8老师: 我妈妈拿签证2016年1月5日进入美国; 如果她7月4日离美行吗?
-Check her I-94 expiration date. She had better leave US before/on the date of her I-94 expiration. If she leaves later than that date, her B-2 visa stamp will be invalid even if it is valid for 10 years, and thus, she has to apply for a new B-2 visa again if she wants to visit US again in the future.
Find her I-94 at this website:
网上说不超过6个月, 如果拿样的话,应该可以; 但是1月5日到7月4日是181天,会不会有问题。
非常感激!
