H-1B Visa Post Doctoral Fellow Jobs
Post Doctoral Fellow positions at U.S. universities and research institutions are among the most H-1B-friendly roles in academia. Employers file the LCA under SOC code 19-1099 or equivalent research scientist classifications, and cap-exempt institutions mean no lottery exposure for most postdoc appointments.

Post-Doctoral Fellow Job Summary
The Department of Chemistry at Colorado School of Mines invites applications for a Postdoctoral Fellow in the Halat Research Group. The successful candidate will develop and apply operando NMR and MRI methods to study electrochemical energy materials under polarization, with emphasis on lithium metal growth, ion transport, interfacial evolution, and spatially heterogeneous behavior in working cells. The position is especially well suited for candidates with experience in battery electrochemistry, operando or in situ characterization, and magnetic resonance methods.
The postdoctoral fellow will design and troubleshoot NMR-compatible electrochemical cells, perform operando NMR and MRI measurements during electrochemical cycling, and integrate those studies with complementary solid-state NMR and related characterization methods to build mechanistic understanding across length scales. The fellow will publish in peer-reviewed journals, present results at conferences, mentor students, and contribute to collaborative proposal development and safe laboratory operations.
Primary Responsibilities
- Develop and execute operando NMR and MRI experiments under electrochemical polarization to probe lithium plating and stripping, ion transport, concentration gradients, interfacial evolution, and spatial heterogeneity in working electrochemical cells, including design and troubleshooting of NMR-compatible cell hardware and workflows.
- Perform complementary solid-state NMR and integrate magnetic-resonance results with electrochemistry and other materials-characterization data to build mechanistic insight into electrochemical processes; analyze complex data sets, prepare manuscripts and presentations, mentor students, and contribute to collaborative project development.
Additional Responsibilities
- Maintain rigorous documentation, data management, instrument readiness, and safe laboratory practices for chemical, electrochemical, and magnetic resonance experiments.
- Performs other duties as assigned.
Minimum Qualifications
- Ph.D. by the start date in Chemistry, Materials Science and Engineering, Chemical Engineering, Physics, or a closely related field, with demonstrated graduate-level research experience in electrochemical energy materials, operando or in situ characterization, magnetic resonance, or a closely related area.
- Demonstrated ability to independently design and execute advanced research experiments; strong background in at least one of the following areas: NMR or MRI, solid-state NMR, battery electrochemistry, lithium metal or lithium-ion materials, or operando or in situ methods; strong quantitative data analysis, scientific writing, and oral communication skills; and the ability to work effectively in a collaborative, interdisciplinary research environment.
Preferred Qualifications
- Ph.D. with direct research experience in operando or in situ magnetic resonance of batteries or other electrochemical systems, especially studies involving lithium metal growth, temperature gradients, low-temperature operation, electrochemical polarization, or spatially resolved transport and structure analysis.
- Experience combining NMR or MRI with complementary characterization or modeling tools such as electrochemical testing, XPS, microscopy, rheology, image reconstruction, or thermal and transport analysis; demonstrated troubleshooting skill for custom experimental setups; and evidence of strong peer-reviewed publication, mentoring, or interdisciplinary collaboration.
Physical Requirements:
- Ability to perform laboratory work in chemistry, electrochemistry, and NMR environments, including prolonged sitting and standing, fine motor work for cell assembly and sample preparation, computer-based data analysis, and occasional lifting or moving of research materials or equipment up to approximately 25 pounds.
Potential Environmental Conditions/Hazards:
- Exposure to chemicals, solvents, battery electrolytes, temperature-controlled equipment, energized electrochemical cells, and strong magnetic fields associated with NMR instrumentation; use of standard laboratory PPE, training, and safety procedures is required.
Anticipated start: August 2026
Total Rewards:
$67,000 annual salary rate

Get Access To All JobsTips for Finding H-1B Visa Sponsorship in Post Doctoral Fellow
Verify your institution's cap-exempt status
Most universities and nonprofit research organizations qualify as cap-exempt H-1B employers, so your petition bypasses the annual lottery entirely. Confirm this directly with your department's HR or international office before accepting an offer.
Request your LCA wage level before signing
Postdoc salaries are often set at DOL wage Level I or II. Cross-check the offered salary against your specific SOC code and work location using the OFLC Wage Search to confirm it meets prevailing wage requirements before you sign.
Gather credential documents early in your search
H-1B petitions for postdoc roles require proof of your doctoral degree and any transcripts showing specialty field alignment. Obtain certified copies and a credential evaluation from a NACES-approved evaluator before your start date approaches.
Filter postdoc roles by H-1B filing history on Migrate Mate
Search postdoc openings on Migrate Mate to see which institutions have active H-1B LCA filing history, so you're targeting employers who sponsor consistently rather than those who treat sponsorship as an exception.
Address specialty occupation proof for your specific project
USCIS scrutinizes postdoc petitions because the title can cover wide-ranging duties. Your offer letter and support letter must tie your specific research project to a theoretical and practical application of your doctoral discipline, not just list generic lab tasks.

Find Post Doctoral Fellow JobsPost Doctoral Fellow H-1B Visa: Frequently Asked Questions
Do most postdoc employers sponsor H-1B visas?
Universities, government-affiliated research labs, and nonprofit research institutions generally do sponsor H-1B visas for postdoc roles and typically qualify as cap-exempt employers, meaning petitions filed on your behalf don't enter the annual lottery. Private-sector research employers may also sponsor but are usually cap-subject. Use Migrate Mate to identify postdoc employers with verified H-1B LCA filing history before applying.
Does a postdoc role qualify as a specialty occupation under H-1B rules?
Yes, provided the position requires a doctoral degree in a specific field directly related to the research duties. USCIS expects the employer to document that a Ph.D. is the normal minimum requirement for the role, not merely preferred. Generic job descriptions listing broad research tasks have drawn Requests for Evidence, so your offer letter and employer support letter should tie duties explicitly to your doctoral discipline.
Can I start a postdoc position while my H-1B petition is pending?
If you're changing status from F-1 OPT or another valid nonimmigrant status, you generally cannot begin work until USCIS approves the petition unless a cap-gap or portability rule applies. Cap-exempt employers can file and request concurrent employment authorization in some circumstances. Confirm the exact start-date rules with your institution's international office and verify current processing timelines on USCIS before committing to a start date.
What happens to my H-1B status if my postdoc appointment ends early?
If your appointment terminates before your H-1B validity period ends, your employer is required to notify USCIS and offer to cover return transportation costs to your home country. You have a 60-day grace period to find new sponsoring employment, change to another nonimmigrant status, or depart. Acting quickly within that window is critical since unlawful presence accrues after it expires.
How does the prevailing wage requirement affect postdoc H-1B sponsorship?
DOL requires your employer to pay at least the prevailing wage for your SOC code and geographic area, certified through the Labor Condition Application before USCIS ever sees the petition. Postdoc salaries at some institutions have historically fallen at wage Level I. You can verify the applicable wage for your specific role and location using the OFLC Wage Search to confirm your offered compensation is compliant before your start date.
