How OPT works
OPT is work authorization for F-1 students, not an employer-sponsored visa. The student applies through their school's international office (the DSO) and USCIS with Form I-765; the employer files nothing. The role must relate to the student's field of study. OPT gives up to 12 months of work authorization, with a 24-month STEM extension for eligible degrees.

Which companies sponsor the most OPT visas for Mechanical Engineers?
WSP has the most, with 32 live OPT jobs on Migrate Mate, followed by Amazon.com (26) and Salas O'Brien (27). Across the 10 companies on this list, Migrate Mate is tracking 174 live OPT jobs, updated daily.
Who is eligible for OPT?
F-1 students who have been enrolled full-time for at least one academic year at a Student and Exchange Visitor Program-accredited school are eligible to apply for OPT. The work must be directly related to the student's field of study. Pre-completion OPT is available before graduation, and post-completion OPT provides up to 12 months of authorization after graduation. Students with STEM degrees may qualify for a 24-month extension.
Do mechanical engineers qualify for F-1 OPT as a specialty occupation?
Yes. Mechanical engineers typically hold a bachelor's degree in a specific field, which is exactly the specialty-occupation standard F-1 OPT is built around. What matters is that the employer classifies the role under a matching occupation code and that your degree lines up with it.
How do I get OPT through a top employer?
To work on OPT, you request authorization through your Designated School Official, who updates your record in the Student and Exchange Visitor Information System and recommends the OPT application. You then file Form I-765 with U.S. Citizenship and Immigration Services and receive an Employment Authorization Document upon approval. The employer does not file anything, once you have your authorization document, you present it to the employer and begin work in a role related to your field of study.
