The STEM Designated Degree Program List governs eligibility for STEM OPT extension applications for F-1 students that are adjudicated by USCIS under the 24-month STEM OPT rule. It was last updated on January 21, 2022 with the addition of 22 qualifying fields of study and their corresponding CIP codes. SEVP has updated the official PDF list on its website, now available at: https://www.ice.gov/doclib/sevis/pdf/stemList2022.pdf. See NAFSA's page DHS Adds 22 Fields to STEM Designated Degree Program List for background on the January 21, 2022 revision.

Note: On the STEM OPT Designated Degree Program List, the following two-digit CIP codes include all four- and six-digit codes within those two-digit series in the CIP taxonomy, including any codes that are subsequently added under those two-digit series in the future:

There are many other CIP codes that are not within the above two-digit series but that have been included on the STEM Designated Degree Program List as "related fields." These other fields are listed by their six-digit CIP code.

The DHS STEM OPT Designated Degree Program List is an exclusive list. CIP codes that are not on this list are not eligible for STEM OPT.
