The Certificate of Eligibility for Nonimmigrant F-1 Student Status (Form I-20) that you submitted lists your program start date as January 11, 2021. Your nonimmigrant status expired on July 26, 2020, which is more than thirty days before the program start date. USCIS may not grant a request for a change of nonimmigrant status to that of an F-1 student that is effective more than thirty (30) days before your program start date listed on your Form I-20.
Because you filed this change of status request before the expiration of your initial period of authorized stay, this application is considered timely filed. However, your initial period of authorized stay expired on July 26, 2020, more than thirty days before your report date or the start of your student program. As such, these additional days are in excess of the statutorily required period and result in your failing to maintain a valid nonimmigrant status, as required.
我的情况是在 3 月 23 号提交了 b1 转 f1 的申请，学校夏季课程是 6 月 8 号开课，i-94 是 7 月 26 号过期。等待结果期间我递交了两次新的 I-20 入学时间，最近的一次 i20 开学时间是 2021 年 1 月 11. 针对拒绝理由 1， 我两次给 uscis 的工作人员打过电话问是否需要填写 extend of status， 第一次是说我可以在美国一直到结果出来，第二次是有明确的回答告诉我的情况不用填写 extend of status 。而且我查询的网站信息也是说我不需要填写 extend of status 。 想问您一下我这样的情况上诉成功可能性大嚒？如果不上诉，但是由于最近回国几乎是不太可能而且费用应该是很高，我在这里停留大概多久会比较合适呢？谢谢您的时间。
If your current nonimmigrant status will expire more than 30 days before your F-1 or M-1 program start date and you wish to remain in the United States until your start date, you must find a way to obtain status all the way up to the date that is 30 days before your program start date (「bridge the gap」). For most people, you will need to file a separate Form I-539 to request to extend your current status or change to another nonimmigrant status, in addition to your other Form I-539 application to change to student status. If you do not file this separate request prior to the expiration of your status, USCIS will deny your Form I-539 request to change to F-1 or M-1 status. Please continue to check the USCIS processing times while your Form I-539 change of status request is pending to determine if you need to file a request to extend or change your nonimmigrant status.
