Get Access To All JobsTips for Finding STEM OPT Authorization as a Performance Engineer
Verify your CIP code before applying
Check your degree's Classification of Instructional Programs code against USCIS's STEM Designated Degree Program List. Computer science, software engineering, and computer engineering codes typically qualify, but information technology programs vary by institution.
Confirm E-Verify enrollment before accepting offers
Search the E-Verify employer search tool to confirm your target company is actively enrolled before you sign anything. A company that isn't enrolled cannot legally employ STEM OPT students, regardless of their intent to sponsor later.
Tailor your I-983 to performance engineering deliverables
Your training plan must map learning objectives to measurable performance outcomes, such as reducing latency benchmarks or improving throughput under load. Generic objectives like 'gain software experience' raise DSO red flags and delay approval.
Target teams with dedicated performance tooling budgets
Performance engineering roles at companies running large-scale distributed systems are more likely to support long-term STEM OPT timelines, since 24 months aligns with typical improvement cycles for capacity planning and reliability programs.
Use Migrate Mate to filter for E-Verify employers hiring Performance Engineers
Search Migrate Mate to surface Performance Engineer roles at employers verified to be E-Verify enrolled. This removes the manual step of cross-referencing job postings against the E-Verify database before you spend time on applications.
Request your H-1B petition before your OPT expires
If your employer files an H-1B visa petition before your STEM OPT end date, cap-gap protection extends your work authorization automatically through September 30. Coordinate with HR at least 90 days before your EAD expiration to meet the April filing window.
Frequently Asked Questions
Does a Performance Engineer role qualify for STEM OPT?
Yes, if your degree is in a STEM-designated field such as computer science, computer engineering, software engineering, or electrical engineering, and the Performance Engineer role directly uses that training. USCIS evaluates the connection between your degree and the job duties, so the role should involve quantitative analysis, systems modeling, or engineering methods rather than general IT support.
What must my employer do to hire me on STEM OPT?
Your employer must be actively enrolled in E-Verify, sign your I-983 training plan, and provide a formal mentoring structure with a supervisor who holds at least a bachelor's degree in a related field. USCIS requires the employer to report any material changes to your training plan to your DSO within five business days.
How do I find Performance Engineer jobs at E-Verify enrolled employers?
Migrate Mate filters Performance Engineer listings by E-Verify enrollment status, so you're only seeing roles at employers who can legally hire STEM OPT students. You can also cross-check any employer using the E-Verify employer search tool before applying, which is especially useful for startups and mid-size companies that may not advertise their enrollment status.
What should my I-983 training plan include for a Performance Engineer position?
Your I-983 should describe specific learning goals tied to measurable engineering outcomes: load testing methodologies, latency profiling, capacity modeling, or reliability engineering frameworks. Vague objectives won't satisfy DSO review. The plan must also detail how your supervisor will evaluate your progress, the tools and environments you'll work in, and how the role connects to your STEM degree field.
What happens to my STEM OPT if my employer files an H-1B petition for me?
If your employer files a timely H-1B cap-subject petition before your STEM OPT EAD expires, cap-gap protection under INA section 214(f) automatically extends your work authorization until October 1 of that fiscal year. You can continue working in your Performance Engineer role without interruption as long as the petition remains pending or is approved.
