Get Access To All JobsTips for Finding Laboratory Jobs at Quest Diagnostics Jobs
Align your credentials to CLIA requirements
Quest Diagnostics operates federally regulated labs under CLIA standards. Before applying, verify your foreign degree or training meets HHS-recognized equivalency, since some H-1B specialty occupation determinations for lab roles hinge on this alignment.
Target high-volume testing sites strategically
Quest operates regional reference labs that process higher specimen volumes and hire more consistently than patient service centers. Prioritizing these locations, often listed by city hub in job postings, improves your odds of landing a role with active sponsorship bandwidth.
Start your job search on Migrate Mate
Use Migrate Mate to filter for open Laboratory positions at Quest Diagnostics that are flagged for visa sponsorship, so you're applying to roles where sponsorship is already part of the hiring conversation rather than an afterthought.
Clarify OPT or CPT status early in interviews
Quest Diagnostics hires F-1 students for lab roles, but hiring managers need lead time to coordinate with HR on authorization. Confirm your OPT start date and STEM extension eligibility upfront so the offer process doesn't stall at the employment verification stage.
Understand the I-129 filing timeline for lab positions
H-1B petitions for laboratory roles at Quest must be filed at least six months before your intended start date if you're cap-subject. Factor in that USCIS standard processing for I-129 petitions can run three to five months, so plan your application timing accordingly.
Track PERM labor certification if pursuing permanent residency
Quest Diagnostics has sponsored Green Cards through the EB-2 and EB-3 categories for laboratory professionals. If long-term sponsorship matters to you, ask during the offer stage whether the role is eligible for PERM filing and what the company's typical timeline looks like.

Find Laboratory at Quest Diagnostics JobsFrequently Asked Questions
Does Quest Diagnostics sponsor H-1B visas for Laboratorys?
Yes, Quest Diagnostics sponsors H-1B visas for Laboratory roles. The company has a consistent history of filing H-1B petitions for clinical and diagnostic laboratory positions across its national network. Roles that require a specific bachelor's degree or higher in a scientific field, such as medical laboratory science or biochemistry, are most likely to qualify as specialty occupations under USCIS criteria.
How do I apply for Laboratory jobs at Quest Diagnostics?
You can search for open Laboratory positions directly on the Quest Diagnostics careers site or use Migrate Mate to browse roles specifically filtered for visa sponsorship eligibility. When applying, tailor your resume to the specific lab discipline listed, whether that's clinical chemistry, hematology, or molecular diagnostics, and address your work authorization status early in the screening process.
Which visa types does Quest Diagnostics commonly use for Laboratory roles?
Quest Diagnostics sponsors H-1B visas as the primary work visa for Laboratory professionals, and also supports TN status for Canadian and Mexican nationals in qualifying scientific roles. F-1 OPT and CPT candidates are hired at the student and early-career level. For longer-term sponsorship, Quest has pursued EB-2 and EB-3 Green Card pathways for laboratory staff in specialized positions.
What qualifications does Quest Diagnostics expect for Laboratory positions?
Most Laboratory roles at Quest Diagnostics require a bachelor's degree in medical laboratory science, clinical laboratory science, biology, chemistry, or a closely related field. ASCP board certification is frequently listed as preferred or required for clinical positions. Hands-on experience with high-complexity testing, laboratory instrumentation, or specimen processing in a CLIA-regulated environment strengthens your candidacy significantly.
How long does the visa sponsorship process take for a Laboratory job at Quest Diagnostics?
For cap-subject H-1B petitions, the process starts with the April lottery, with employment typically beginning October 1 at the earliest. USCIS standard processing for the I-129 petition runs three to five months after filing. If you're transferring an existing H-1B, Quest can file a transfer petition and you can begin working once it's received. TN status for Canadian nationals can be obtained at a port of entry with a same-day decision.
