我今年的好几个来美国读书的学生，持B1入境，都是先去了夏校。然后有的学生是回国，再签F。有的直接入读美国的学校，具体的操作过程。我把我给学生的这个粘贴过来，希望能帮到你！

Here is what you need to know/do to make this process go smoothly:

· You will be entering the US with your B-1/B-2 visa. Your F-1 visa will not be 'active' yet.

·
· Before your summer program ends, you will need to apply for a 'Change of Non-Immigrant Status'. This process can be done by using USCIS ELIS (an online system) and filling out Form I-539. You will need a couple of things:

· A copy of your signed I-20

· A copy of your I-94 with the 'prospective student' mark on it

· A bank statement (just like the one you provided to us when you first applied to Stuart, this is just to prove that you have enough funds to attend school here)

· $195.00, which is the I-539 standard fee.
An essay of statement why you want to change your status of B1

Make sure you don't wait until the very last minute to apply for the change of status - even though you will be fine if the case is still processing, ideally you'd want to make the switch to an F-1 just in time for school to start. Not a big deal if it goes over for a few days/weeks though, as long as you don't have any intents of leaving the country.

有两种方法：
1，从美国的移民法来说，你拿B1签证入美国境内，如果不想离开美国，可以用Form I-539这种申请表来申请转换学生身份，但这种转换身份并不是F1签证，当你的I-539成功获得批准后，你在美国就是学生身份，可以合法地在美国读书，只要你不离境并且你的I-20有效，那么，你学生身份就有效；
2，离开美国回到祖国申请学生签证。这种操作比在美国用I-539转换身份容易得多。因为在美国申请转换身份会要求你提供资产证明、以及你要对你从b1签证转成学生身份的合理说明等等以及其它相关说明。我成功地办理过两个学生在美国由B1转换成学生身份，但我觉得在美国转换身份比学生在国内申请F1签证复杂很多。建议直接回国申请F1签证。

回来申请面签。找个合适的面签时间就好。

回国换F1签证！保持良好签证记录！

这么晚还被录取?! 能说说什么学校吗 回来签证
