OPT / STEM OPT Eligibility Calculator
Calculate your OPT application filing window, check whether you qualify for the 24-month STEM OPT extension, and see all critical dates on a single timeline. Enter your graduation date and program details to get started.
How This Tool Works
Enter your expected graduation date, degree level, whether your program is STEM-designated, and your current OPT status. The tool calculates your 150-day OPT filing window (90 days before to 60 days after graduation), your 12-month OPT validity period, and, if you are in a STEM program, the 24-month STEM OPT extension timeline. All dates are computed using federal OPT regulations, and results are displayed in an interactive timeline.
What the Data Covers
OPT filing windows and validity periods are based on 8 CFR 274a.12(c)(3)(i) and USCIS OPT regulations. The 90-day pre-completion and 60-day post-completion filing windows are set by federal regulation. The STEM OPT extension rules follow the 2016 final rule (81 FR 13040), which established the 24-month extension for qualifying STEM fields. The DHS STEM Designated Degree Program list is maintained by ICE and updated periodically. Grace period rules follow standard F-1 regulations (8 CFR 214.2(f)).

Data Source & Methodology
OPT filing windows are determined by federal regulation: 8 CFR 274a.12(c)(3)(i) sets the 90-day pre-completion and 60-day post-completion application window. The 12-month OPT duration is statutory under INA 101(a)(15)(F)(i). STEM OPT extension rules follow the 2016 DHS final rule (81 FR 13040), which replaced the previous 17-month extension with a 24-month extension. The E-Verify employer requirement and I-983 training plan obligation are part of the same regulation. Processing time estimates are based on published USCIS Form I-765 median processing times for the OPT category.
OPT rules have important nuances: USCIS processing delays can affect your start date, unemployment day limits apply during OPT (90 days for initial OPT, 150 days with STEM extension), and program changes or transfers can reset eligibility. Always confirm your specific situation with your Designated School Official (DSO) and, if needed, a licensed US immigration attorney.
