DHS 웹사이트에서는 졸업한지 10년이내에 예전STEM학위를 이용한 STEM extension이 가능하다고 되어 있네요.

Under certain circumstances, an F-1 student may use a prior STEM degree from a currently accredited SEVP-certified school to fulfill this eligibility requirement. To use a prior degree to qualify for the STEM OPT extension, the F-1 student must:
– Have received their most recent degree (which does not need to be STEM-related) from a currently accredited Student and Exchange Visitor Program (SEVP)-certified school.
– Have received their prior, qualifying STEM degree* (at the bachelor’s level or higher) within 10 years of applying for the STEM OPT extension with USCIS.
– The qualifying STEM degree needs to be on DHS’s STEM Designated Degree Program List at the time the student submits their application for the STEM OPT extension, rather than at the time that the student received the degree.
