j签证豁免要多久？
我今年7月2号在波士顿J签入境的，6.18那天刚刚拿到豁免。我们是在网上填了表格然后寄到移民局那里，他们审查之后会发邮件给你。我的邮箱是5年有效期的护照上原来用的那个，所以一直都没有收到过任何邮件（怀疑是因为这个原因所以才让我等了半年）。后来给移民局打电话才找到了我所有的邮件都发到新的邮箱里了。 电话打过去以后跟客服小姐说了情况，她说他们会重新再给我发一次信。结果第二天就收到了email说他们已经把我之前的资料又递交给上级审查了（不知道是不是因为我打电话的缘故）。 我觉得可能因为我是自己主动去联系的缘故吧。如果同学们实在等不及的话也可以像我一样打个电话试试。
下面是一些关于豁免的信息，希望可以帮到大家 【I-901】
【J1】/V92， V94(AOS) J1 Visa Waiver Application Form I-901， and Instructions for Completing the Form (PDF， 13 pp， 351K， August 2011 ) This is a new form to be used by all J visa holders with nonimmigrant status valid through January 3， 2013， or later who wish to enter as a J visitor instead of applying for an adjustment of status in the United States. You must fill out this form to get an I-94W Arrival and Departure Record. It costs $160 per person， but does not include processing fees required at U.S. land ports of entry. You may pay online using a credit card. The money goes directly into the U.S. Treasury without touching government offices’ budgets. Your receipt number should be included on your form I-901 along with other information requested．You will need it when you apply at the embassy or consulate that issued your visa．It takes about one year before a waiver can be approved after filling out this form； therefore， if you are already in the USA， don’t waste time trying to find waivers because they do not exist！ Instead， check with consulates in countries where you have visas to see if there are alternate ways for getting them to issue you new Visas so you can leave the country， and return legally as tourists！ Check with consular website for info on their local process， whether it involves a separate application or if there is only additional paperwork needed once they receive your passport with the previous visa stamped inside. Do this regardless of how long it has been since you were last outside the US！ If your travel plans change while waiting for approval， contact the Embassy／Consulate immediately. They might let you proceed even though you did not complete everything yet; however， such exceptions happen rarely. Please also note that submitting the form does NOT guarantee waiver approval！ Some cases may require more evidence than what
