The H1b visa only approves foreign employees who work in a Specialty Occupation. When USCIS decides whether a position qualifies as a specialty occupation, the core question is: Does the position "normally" require at least a bachelor's degree (or equivalent) in a related specialty to perform it?

To prove this, the strongest evidence comes from official U.S. / industry-recognized occupational databases. The three websites below are all free, public, and widely accepted by attorneys and USCIS. This article explains the purpose of each website, the lookup steps, and which fields you should capture.

Have two things ready first

1. The English job title, e.g. Software Developer, Financial Analyst.
2. The SOC Code (Standard Occupational Classification code), e.g. 15-1252.00. If you don't yet know the matching SOC Code, see Common Occupations and SOC Codes first, or use the O*NET search below to find it.

1. O*NET OnLine — Duties, Skills, and Required Education Level

O*NET OnLine is funded by the U.S. Department of Labor (DOL) and is the current official occupational classification system (it has replaced the old DOT Code). It is best for describing the complexity of a position's duties and the level of specialized knowledge required.

Lookup steps:

1. Open onetonline.org and enter the job title (or the SOC Code directly) in the Occupation Search box at the top right.
2. In the results, select the occupation that best matches the real duties and open its Summary Report.
3. Focus on the following sections:
   • Job Zone: This is the most important field. Job Zone 4 — Considerable Preparation Needed generally corresponds to "requires a bachelor's degree," and Job Zone 5 — Extensive Preparation Needed generally corresponds to a graduate degree. Job Zone 4 and above is strong evidence supporting a specialty occupation.
   • Education: Shows the typical education distribution of workers (e.g., the share holding a Bachelor's degree).
   • Tasks / Work Activities: Lists the core duties of the position, used to demonstrate the "specialization and complexity" of the work.
   • Knowledge / Skills: Describes the specialized knowledge fields the position requires, which can be matched to the beneficiary's academic background.

When you can't find an exact SOC

Use the O*NET Code Connector and enter the job title or duty keywords to map a non-standard job title to the closest O*NET/SOC occupation.

2. CareerOneStop — Typical Entry Education and Certification Requirements

CareerOneStop is also sponsored by the U.S. Department of Labor and has a more user-friendly interface. It is best for getting the typical entry education and related certifications/licenses in one place.

Lookup steps:

1. Open careeronestop.org and use the top search or go to Explore Careers → Occupation Profile.
2. Enter the job title, select the matching occupation, and open the Occupation Profile.
3. Focus on:
   • Typical Education / Education needed for entry: The typical minimum education for entering this position (e.g., Bachelor's degree).
   • Knowledge / Skills / Abilities: Cross-confirms with O*NET.
   • Certifications / Licenses: If the position requires an industry certification or license, this can serve as supplementary evidence of "specialization."
   • Wages: View the salary range by state/region to help understand wage compliance (the actual prevailing wage on the LCA prevails).

3. OOH (Occupational Outlook Handbook) — Entry-Level Education, the Most Authoritative Single Citation

The Occupational Outlook Handbook is published by the U.S. Bureau of Labor Statistics (BLS) and is the source most frequently cited by attorneys in RFE responses. Its "How to Become One" section states the "entry-level education requirement" most clearly and authoritatively.

Lookup steps:

1. Open bls.gov/ooh and find the occupation by browsing categories or using the site search.
2. Once on the occupation page, switch to the How to Become One tab.
3. Focus on:
   • Entry-Level Education: The entry-level education requirement. If it shows Bachelor's degree, that is the most direct single sentence proving a specialty occupation.
   • The "field of study / major" description in the body text: Indicates that the position typically requires a degree in a specific specialty (a specialty occupation requires a degree in a "specific specialty," not just any degree).
   • Important Qualities / What They Do: Additional support for the specialization of the position.

Why OOH matters most

The core point of contention for a specialty occupation is "whether a bachelor's degree in a specific specialty is required." When OOH clearly states Bachelor's degree and identifies the field of study, it is the cleanest official citation when responding to a USCIS challenge (RFE).

4. Comparison of the Three Websites

Website	Publisher	Best for looking up	Use in H1b
O*NET OnLine	DOL	Job Zone, core duties, required knowledge and skills	Proving the specialization and complexity of the duties
CareerOneStop	DOL	Typical entry education, certifications/licenses, wages	Confirming the education threshold, supplementary certification requirements
OOH (BLS)	BLS	Entry-Level Education, field of study	Proving a "bachelor's degree in a specific specialty is required"; most authoritative citation

5. How to Use This Information in an H1b Application

USCIS evaluates a specialty occupation mainly against four criteria (8 CFR 214.2(h)(4)(iii)(A)), and the three websites above directly support the first two:

• The position normally requires a bachelor's or higher degree → Use OOH's Entry-Level Education + CareerOneStop's Typical Education.
• The degree requirement is common to the industry in parallel positions → Use O*NET's Job Zone (level 4 and above) + the consistent education data across all sites.
• The duties themselves are specialized and complex → Use O*NET's Tasks / Knowledge / Skills descriptions.
• The degree matches the field of study → Map the field of study the position requires to the beneficiary's degree major.

Don't force-fit a SOC just for the lottery or wage

When choosing a position and SOC Code, it must match the real duties; when confirming, you should simultaneously cross-check the job title, core duties, minimum education/experience, work-location wage, and wage level. See Common Occupations and SOC Codes for details.
