Uscis 에 따르면 (https://www.uscis.gov/i-9-central/complete-correct-form-i-9/complete-section-1-employee-information-and-attestation/foreign-academic-students)
:

The following documents establish the student’s identity and employment authorization for Form I-9 purposes:

Unexpired EAD (List A), or
Expired EAD presented with Form I-20 endorsed by the student’s Designated School Official (DSO)(List A). Note: this is acceptable for 180 days from the expiration date on the card and work authorization must be reverified after 180 days for employment to continue.
If the student presents an expired EAD and an endorsed Form I-20 as described above, the employer should enter the following information under List A in Section 2 of Form I-9:

The EAD document title
The EAD document number
The date the EAD expired in the expiration date space, and
“180-day Ext.”

오 답변 감사합니다!!ㅎㅎ

제가 OPT는 많이 안해봐서 조금 조심스럽지만, OPT는 180일 Automatic Extension 의 혜택을 받지 못하는 유형으로 생각됩니다. https://www.uscis.gov/working-united-states/automatic-employment-authorization-document-ead-extension
위의 웹페이지에 automatic extension 에 해당되는 유형이 나열되어 있는데, OPT 는 “c 3” 에 해당됩니다(Form I-765 Instruction pages 3-4). 아쉽게도, c3 는 포함되어 있지 않는 것으로 보입니다.

시애틀 이변호사님,

https://www.uscis.gov/opt
에 따르면, 아래와 같이 설명되어있는데요. 그리고 많은 분들이 이렇게 알고계십니다.

If you file your STEM OPT extension application on time and your OPT period expires while your extension application is pending, we will automatically extend your employment authorization for 180 days. This automatic 180-day extension ceases once USCIS adjudicates your STEM OPT extension application.

네 맞는 말씀이십니다. 의견 감사합니다.
