Continuing Students - May renew their visas at any time, as long as they have maintained student status and their SEVIS records are current. Continuing students may enter the United States at any time before their classes start.作者: 匿名 时间: 2017-7-12 15:16
你是用新的SEVIS还是原来旧的那个？SEVIS没换的话应该就可以随时入境。换了就只能提前三十天入境。我之前同一个学校读本科跟研究生。但是因为研究生的时候SEVIS号码换了所以也是只能提前三十天入境。作者: 匿名 时间: 2017-7-12 15:32
