妈妈去年中提交了I539 延期申请（旅游签证），当时寄539表的时候，我是帮我妈妈准备资料和interpreter的人。妈妈已经离开美国将近半年，现在我们家换了房子，地址变了。我们是H1b, 需要去移民局官网改一下地址。但是妈妈延期申请还没有出结果，我是否也需要去移民局官网帮妈妈改一下地址？谢谢8老师
-It does not matter, but you had better file change of address for her so that you can receive the denial notice for her. In the future, she had better bring the evidences of her leaving such as flight boarding card, entry stamp on her passport by Chinese Customs officer, and the I-539 Receipt Notice (and denial notice) when she comes to US again in case the IO in the port of enttry may ask for these documents. These documents prove that she left US during the I-539 pending so that her B2 visa is not affected.
Read this link for the address change for her pending case:
