我重新翻找了官方声明,如果你现在处于automatic cap-gap extension. 理论上是要申请新的h1b的,请看 Q6. May students travel outside the United States during a cap-gap extension period and return in F-1 status? A6. No. A student granted a cap-gap extension who elects to travel outside the United States during the cap-gap extension period will not be able to return in F-1 status. The student will need to apply for an H-1B visa at a consular post abroad prior to returning. As the H-1B petition is for an October 1, 2012 start date, the student should be prepared to adjust his or her travel plans, accordingly. source: http://www.uscis.gov/portal/site/uscis/menuitem.5af9bb95919f35e 如果要申请新的h1b visa的话,可以在其生效前三个月预约,最早可以在9月20日持h1b visa入境
