Aerospace & Defense Companies That Sponsor CPT
Aerospace and defense companies hire F-1 students for CPT roles in mechanical engineering, systems analysis, software development, and research, though ITAR and security clearance requirements limit which positions are open to foreign nationals. Boeing, Lockheed Martin, Northrop Grumman, RTX, GE Aerospace, and SpaceX run large internship programs that regularly include CPT students on unclassified projects. Browse aerospace employers offering CPT-eligible positions by role type, clearance requirements, and current openings. For detailed visa eligibility requirements, see the official USCIS guide.

How to Get Visa Sponsorship in Aerospace & Defense Companies That Sponsor CPT
Target Unclassified Programs First
F-1 students aren't eligible for security clearances. Focus on commercial aviation, space systems, and R&D divisions that operate outside ITAR-restricted programs. Job postings with no clearance requirement listed are your best signal.
ITAR Restrictions Vary by Role
ITAR limits access to certain defense technical data to U.S. persons, but many aerospace employers have ITAR-exempt projects or obtain TAAs that allow foreign nationals to contribute. Ask hiring managers directly whether the role involves controlled data.
Align Your Major to the Role
CPT requires a direct connection between coursework and job duties. Aerospace employers hire for mechanical, electrical, computer science, and systems engineering co-ops. Confirm with your DSO that the specific job description qualifies before accepting.
Apply to Established Internship Programs
Lockheed Martin, Boeing, Northrop Grumman, RTX, and General Dynamics run large-scale programs that regularly include F-1 CPT students. These companies have immigration coordinators who can provide DSO-compliant documentation without delays.
Start the DSO Process Early
Aerospace contractors often extend offers 3 to 6 months before start date. Your DSO needs the signed offer letter 2 to 4 weeks before issuing the CPT I-20. Start the conversation with your international student office as soon as you have an offer.
Use Career Fairs With Defense Presence
L3Harris, BAE Systems, and Leidos recruit at engineering career fairs with recruiters trained on visa questions. Ask whether the specific team works on unclassified projects and has hired CPT students before.

Search All CompaniesFrequently Asked Questions
Can F-1 students on CPT work at defense contractors?
Yes, but only on projects that don't require a security clearance or access to ITAR-controlled technical data. Boeing, Lockheed Martin, RTX, and Northrop Grumman all have commercial and unclassified divisions that regularly hire F-1 students for engineering internships and co-ops. Look for postings that explicitly state 'no clearance required' to filter eligible roles.
Do ITAR restrictions prevent F-1 students from working in aerospace?
Not entirely. ITAR restricts access to specific defense articles and technical data, but aerospace companies also work on commercial aviation, satellite communications, and space exploration projects that fall outside ITAR controls. Some employers like Boeing and GE Aerospace obtain export licenses or TAAs that permit foreign national participation on certain otherwise-restricted programs.
Can I get a security clearance on CPT?
No. Security clearances require U.S. citizenship or, in rare cases, permanent residency. F-1 students on CPT are not eligible under any circumstances. Focus your aerospace job search exclusively on roles that list no clearance requirement. Commercial divisions at Boeing, SpaceX, and GE Aerospace have the highest concentration of clearance-free engineering positions.
Will aerospace companies provide the CPT offer letter my DSO needs?
Major employers with established internship programs will. Boeing, Lockheed Martin, RTX, and Northrop Grumman have HR teams familiar with CPT documentation and will issue detailed offer letters specifying job duties, dates, hours, and supervisor information. Smaller defense subcontractors may need you to provide a template or your DSO's specific requirements.
Does part-time CPT work in aerospace affect my OPT eligibility?
No. Part-time CPT (20 hours or fewer per week during the academic term) does not count toward the 12-month full-time CPT limit that eliminates OPT eligibility, regardless of how many semesters you use it. Only cumulative full-time CPT exceeding 12 months triggers the OPT restriction. A single summer of full-time CPT (10 to 12 weeks) won't reach that threshold.
