OPT extension, I765 Question 17 只写了degree level, 没写major

大家好，我想问一个i765填写的问题。我6月13号申请 OPT extension, 状态至今为止仍然是 case was received。
今天在网上翻看各种关于OPT extension 申请的帖子，发现有的学校建议同时将degree level和major 填到 i765 question 17 [(c)(3)(C) Eligibility Category] 中的degree的那个格子里, 然后我当时并没有填major。
换句话说，degree blank for question 17 中，我只填了 M.S.， 网上却建议填 M.S. 14.1001 (I20上EE major的编码)。
想请教各位申请过extension朋友，这个算不算一个重大失误，会不会影响结果，我需不需要寄一个修订的i765给USCIS?
谢谢了。

一个advisor电话告诉我不是啥大问题，然后给我读i765 instructions (from USCIS)里的这段话：
F-1 Student Seeking Optional Practical Training (OPT) in an Occupation Directly Related to Studies:
(c)(3)(A)--Pre-completion Optional Practical Training; (c)(3)(B)--Post-completion Optional Practical
Training; (c)(3)(C)--24-month Extension for STEM (Students With a Degree in Science, Technology,
Engineering, or Mathematics) Optional Practical Training. File Form I-765 with a Certificate of Eligibility
of Nonimmigrant (F-1) Student Status (Form I-20 A-B/I-20 ID) timely endorsed by a Designated School Official
(DSO) (DSO’s recommendation within the past 30 days for Post-Completion OPT and 60 days for the 24-month
STEM OPT extension). If you are requesting a 24-month STEM OPT extension under the eligibility code
(c)(3)(C), you must submit a copy of your degree and the employer name as listed in E-Verify, along with
the E-Verify Company Identification Number, or a valid E-Verify Client Company Identification Number for
the employer with whom you are seeking the 24-month OPT extension. You must provide this information in
Question 17 of the form.

关于要不要写both官方也没有答案。官方并没有明确指出。

第二个advisor邮件回复：
Do not send USCIS another I-765.  This will just confuse matters.

I don’t think this is an issue of concern.  The USCIS adjudicator can see the CIP code assigned to your major on your I-20. If the adjudicator does has questions, then a Request for Further Evidence (RFE) will be sent.  Have you been tracking the status of the case on line?

重点是不建议寄新的i765，我目前还没有收到任何RFE。

不要紧，你I20上面有，他们会查的

多谢，我想着这几天估计也会出结果，实在不行就等RFE。学校那边我也问了下，收到回复后会在这个帖子里分享。

这种细节没有官方答案,各个学校的建议都不太一样，我觉得他有I20不会rfe你的

我觉得你说的很有道理。刚刚接到学校的电话，和你说的基本一致。他们说见到过只填degree level的，也见到过只填major code的，最后貌似都通过了。

这里copy一下 USCIS official filing instruction for i765 中关于question 17的全部描述：

F-1 Student Seeking Optional Practical Training (OPT) in an Occupation Directly Related to Studies:
(c)(3)(A)--Pre-completion Optional Practical Training; (c)(3)(B)--Post-completion Optional Practical
Training; (c)(3)(C)--24-month Extension for STEM (Students With a Degree in Science, Technology,
Engineering, or Mathematics) Optional Practical Training. File Form I-765 with a Certificate of Eligibility
of Nonimmigrant (F-1) Student Status (Form I-20 A-B/I-20 ID) timely endorsed by a Designated School Official
(DSO) (DSO’s recommendation within the past 30 days for Post-Completion OPT and 60 days for the 24-month
STEM OPT extension). If you are requesting a 24-month STEM OPT extension under the eligibility code
(c)(3)(C), you must submit a copy of your degree and the employer name as listed in E-Verify, along with
the E-Verify Company Identification Number, or a valid E-Verify Client Company Identification Number for
the employer with whom you are seeking the 24-month OPT extension. You must provide this information in
Question 17 of the form.

这里关于STEM extension说到四点：
1. time endorsed I20 recommending STEM extension，60 day rule for extension
2. copy of degree
3. employer name as listed in E-verify
4. the E-Verify Company Identification Number for the employer

information about degree, 3，and 4必须在 i765 question 17中提供。

然而，这里并没有提到what kind of information about degree需要在question 17提供。这就导致学校也不确定。

当然，能把degree level和major code一起写上最好，但是，如果空太小写不下那另说。

刚刚又收到学校的邮件回复，是另外一个advisor发的邮件：

Do not send USCIS another I-765.  This will just confuse matters.

I don’t think this is an issue of concern.  The USCIS adjudicator can see the CIP code assigned to your major on your I-20. If the adjudicator does has questions, then a Request for Further Evidence (RFE) will be sent.  Have you been tracking the status of the case on line?

不会的。把心放在肚子里

8.30变成制卡状态，目前看来没受影响
