E-3 Visa Physics Jobs
Physics roles in the U.S. span national laboratories, university research departments, semiconductor firms, and defense contractors, most of which routinely offer E-3 visa sponsorship for Australian candidates. The E-3 requires a bachelor's degree in physics or a closely related field, has no lottery, and renews in two-year increments without limit.

Get Access To All JobsINTRODUCTION
A postdoctoral fellow position is available in the department of Radiation Physics. This position focuses on the development and implementation of cutting-edge AI solutions for radiotherapy. The successful candidate will join a dynamic research team dedicated to developing an end-to-end deep learning framework for autonomous 3D dose calculation and VMAT optimization. The primary focus of this role is the development of generative models (e.g., Diffusion models, Transformers) to predict optimal machine parameters.
All duties and responsibilities are carried out in compliance with institutional policies, ethical research standards, and applicable federal and state regulations.
LEARNING OBJECTIVES
The primary objective is to gain advanced expertise in developing complex AI architectures for medical applications. The fellow will learn to integrate AI-driven solutions into radiotherapy workflows, specifically for VMAT planning, 3D dose calculation, and machine parameter optimization. Furthermore, the program will enhance the candidate's scientific writing skills and provide practical experience in the clinical application of medical physics.
ELIGIBILITY REQUIREMENTS
Applicants must hold a Ph.D. in Medical Physics, Computer Science, Electrical Engineering, or a closely related quantitative field. A strong proficiency in Python and PyTorch is essential, along with extensive experience in medical image processing and deep learning frameworks. Additionally, candidates are required to demonstrate a proven track record of academic excellence through peer-reviewed publications in reputable journals.
POSITION INFORMATION
MD Anderson offers full-time postdoc positions with a salary ranging from $64,000 to $76,000 depending on the number of years of postgraduate experience. The University of Texas MD Anderson Cancer Center offers excellent benefits, including medical, dental, paid time off, retirement, tuition benefits, educational opportunities, and individual and team recognition.
Offsite work arrangements are subject to approval and may be modified or revoked at any time based on business needs, performance considerations, or regulatory requirements.
This position may be responsible for maintaining the security and integrity of critical infrastructure, as defined in Section 113.001(2) of the Texas Business and Commerce Code and therefore may require routine reviews and screening. The ability to satisfy and maintain all requirements necessary to ensure the continued security and integrity of such infrastructure is a condition of hire and continued employment.
It is the policy of The University of Texas MD Anderson Cancer Center to provide equal employment opportunity without regard to race, color, religion, age, national origin, sex, gender, sexual orientation, gender identity/expression, disability, protected veteran status, genetic information, or any other basis protected by institutional policy or by federal, state or local laws unless such distinction is required by law.

Get Access To All JobsTips for Finding E-3 Visa Sponsorship as a Physics
Translate your Australian credentials for U.S. employers
A three-year Australian physics degree is generally treated as equivalent to a U.S. four-year bachelor's by USCIS. Confirm this equivalence in writing with a credential evaluation service before your first interview so you're not fielding the question mid-process.
Target employers with active DOL LCA filings
National laboratories, semiconductor manufacturers, and defense contractors file Labor Condition Applications with the DOL before every E-3 hire. Searching the DOL's OFLC disclosure data for 'physicist' or 'research scientist' job titles shows which employers have done this recently and understand the process.
Distinguish specialty occupation roles from general science positions
Not every physics-adjacent job title qualifies as a specialty occupation under E-3 rules. Roles where the position description explicitly requires a degree in physics, applied physics, or a directly related field are far more defensible at the consulate than postings listing 'bachelor's preferred' in any STEM discipline.
Get your LCA and visa paperwork filed through Migrate Mate
Once you have a job offer, use Migrate Mate's E-3 filing service to handle your LCA and visa paperwork. The LCA must be certified by the DOL before your consulate appointment, and errors at this stage are the leading cause of delays for physics candidates.
Address security clearance requirements early in negotiations
Many U.S. physics roles, particularly at national labs and defense contractors, require security clearances that Australian nationals cannot hold at the highest levels. Clarify clearance requirements before accepting an offer so sponsorship discussions aren't derailed after the LCA is already filed.
Prepare for specialty occupation scrutiny at the consulate
Consular officers at Sydney, Melbourne, and Perth may probe whether your specific role genuinely requires a physics degree rather than broader STEM training. Bring your employer's LCA, a detailed job description, and documentation showing how your degree directly maps to the role's core responsibilities.

Find Physics JobsPhysics E-3 Visa: Frequently Asked Questions
How do I find Physics jobs with E-3 visa sponsorship?
Migrate Mate is built specifically for this search. It filters Physics roles by employers with E-3 sponsorship history, so you're not cold-applying to companies unfamiliar with the visa. National laboratories like Argonne, Sandia, and Lawrence Berkeley, along with semiconductor and defense firms, are the most active sponsors for physics candidates in the U.S.
How much does it cost to get an E-3 visa?
Migrate Mate's E-3 filing service covers the entire process for $499, including the Labor Condition Application, visa document preparation, and consulate appointment guidance. Traditional immigration lawyers charge $2,000–$5,000+ for the same work. The E-3 has less paperwork than most work visas, so paying thousands for legal help is usually unnecessary.
Does a three-year Australian physics degree qualify for the E-3?
Yes, in most cases. USCIS and consular officers generally treat a three-year Australian bachelor's degree as equivalent to a U.S. four-year degree for E-3 specialty occupation purposes, provided the degree is in a field directly related to the role. A formal credential evaluation can document this equivalence if your employer or the consulate requests it.
How does the E-3 compare to the H-1B for physics professionals?
The E-3 has no annual lottery, so there's no random selection risk that can leave you without status after a job offer. It's available year-round and can be approved at the consulate in days rather than months. The H-1B has an 85,000-slot annual cap, a competitive lottery, and a standard processing window measured in months, making the E-3 a substantially more predictable path for Australian physics candidates.
Can I change physics employers after I'm already on an E-3?
Yes, but each new employer must file a fresh LCA with the DOL and you'll need a new visa stamp or an I-94 update reflecting the new employer before you start work. There's no portability provision like the H-1B's AC21 rule, so the transition requires coordination between your incoming employer and your consulate or port of entry. Plan at least four to six weeks for the LCA certification step.
