Quick answer
An H1B visa is the specialty-occupation work visa. The employer registers the beneficiary in the annual March lottery. If selected, the employer files Form I-129 with USCIS, including the Labor Condition Application and evidence the role qualifies as a specialty occupation. After approval, the beneficiary completes DS-160 with a compliant photo, pays the MRV fee, and attends a consular interview to receive the stamped H1B in their passport.

What H1B actually is
H1B is the work visa for "specialty occupations," defined under INA section 214(i) as roles requiring theoretical and practical application of a body of highly specialized knowledge along with a bachelor's degree or higher (or equivalent) in the specific specialty as a minimum entry requirement.
That definition does a lot of work. It excludes roles that any high school graduate could perform regardless of how technical the job title sounds. It excludes roles where a generic bachelor's in any field is acceptable. It excludes generalist business roles where the specialty connection is loose. USCIS scrutiny of "specialty occupation" has tightened significantly over the past decade, and the burden of proof sits with the employer to show the role meets the test.
The H1B is capped at 65,000 visas per fiscal year in the regular cap and an additional 20,000 reserved for beneficiaries holding US master's degrees or higher (the "master's cap"). Some employers are cap-exempt: institutions of higher education, nonprofit research organizations affiliated with higher education, and government research organizations can file H1B petitions year-round without entering the lottery.
H1B is also one of the few non-immigrant categories with built-in dual intent. The Department of State and USCIS both accept that an H1B holder can simultaneously pursue a green card without triggering 214(b) concerns. This is why H1B has become the primary pipeline from F1 OPT to employment-based green card.
Initial H1B is granted for 3 years. It can be extended to 6 years total. AC21 extensions beyond 6 years are available when an employment-based green card process is sufficiently advanced (approved I-140, or PERM filed more than 365 days before extension).
The electronic registration process
USCIS introduced the electronic registration system in 2020 to replace the paper lottery. The annual registration window opens in March. Each employer (or attorney on behalf of the employer) submits a short registration per beneficiary, paying a small per-registration fee. No supporting documents are filed at this stage; only minimal beneficiary information and employer details.
Within the registration window, USCIS runs the lottery using the beneficiary-centric model adopted starting fiscal year 2025. Under beneficiary-centric selection, USCIS picks unique beneficiaries rather than registrations. If multiple employers register the same beneficiary, the beneficiary still has only one entry in the lottery. This change ended the practice of submitting the same beneficiary under many shell companies to inflate lottery odds.
USCIS runs the lottery in two passes:
- Master's cap pass: a random selection of beneficiaries holding US master's degrees or higher, up to the 20,000-visa master's cap.
- Regular cap pass: a random selection from the remaining pool (including unselected master's cap beneficiaries), up to the 65,000-visa regular cap.
USCIS announces selections by the end of March. Selected employers receive a notice in the registrant's myUSCIS account, and the filing window for I-129 opens April 1 and runs through approximately late June. If demand falls short of the cap, USCIS may run additional selections later in the year.
Unselected beneficiaries cannot file I-129 that fiscal year and must wait for the next March registration window. Many remain on F1 OPT or STEM OPT while waiting, or shift to L1 or O1 if eligible.
I-129 petition by the employer
If your registration is selected, your employer files Form I-129 (Petition for a Nonimmigrant Worker) with H1B supplement and supporting evidence. This is where the case is actually adjudicated.
The I-129 packet typically includes:
- Form I-129 and H1B supplement: the main petition form.
- Labor Condition Application (LCA, Form ETA-9035): filed with the Department of Labor before I-129. The LCA establishes the prevailing wage for the role and the worksite, and the employer attests to paying at or above prevailing wage.
- Specialty occupation evidence: job description, organizational chart, education and experience requirements for the role, USCIS decisions in similar cases. The employer must show the role normally requires a bachelor's degree in a specific specialty.
- Beneficiary qualifications: diplomas, transcripts, work experience letters, professional licenses. Foreign degrees usually need a credentials evaluation showing equivalence to a US bachelor's or higher.
- Employer-employee relationship evidence: for IT consulting and similar third-party placement models, USCIS requires evidence that the petitioning employer has actual control over the beneficiary's work (project plans, timesheets, end-client agreements).
- Filing fees: I-129 base fee, ACWIA training fee (depending on employer size), fraud prevention fee, Public Law 114-113 fee for large H-1B-dependent employers, and the optional premium processing fee.
Premium processing is heavily used at the I-129 stage. For an additional fee, USCIS guarantees adjudication within 15 business days. Most cap-cases use premium processing to lock in the October 1 start date without uncertainty.
USCIS either approves, denies, or issues a Request for Evidence (RFE). RFEs are common in H1B; they typically ask for additional specialty occupation evidence or beneficiary qualifications. Response deadlines are tight, usually 60 to 87 days.
Consular stamping after approval
After I-129 approval, USCIS issues Form I-797 approval notice. If the beneficiary is outside the United States, they need to attend a consular interview to receive the H1B visa stamp before entering. If the beneficiary is already in the US (typically on F1 OPT or H4), they may not need to leave for stamping until their first international trip, because change of status was approved as part of I-129.
The stamping process:
- Complete DS-160: fill the non-immigrant visa application, upload a compliant photo, and save the confirmation page.
- Pay MRV fee: pay the consular fee through the country's designated channel.
- Schedule biometrics and interview: book appointments on the country's visa appointment portal. Many H1B applicants qualify for dropbox if they previously held H1B and meet the renewal criteria.
- Attend biometrics: fingerprints and a fresh photo are captured at the Visa Application Center.
- Attend the interview: bring I-797, employer letter, recent pay stubs (for renewals), LCA, beneficiary qualifications, DS-160 confirmation, MRV receipt, photo backup, and passport.
Typical H1B interview questions cover the employer (size, business model, address), the role (title, responsibilities, salary), the specific project (client, location, technology stack), the beneficiary's qualifications (degree, experience, why they fit the role), and the trip purpose. Officers may also ask about itinerary, length of intended stay, and family in the United States.
Administrative processing under 221(g) is common for H1B because the case may go through additional background checks (FBI name check, technology screening) before issuance. Cases sometimes take weeks to months to clear administrative processing. Avoid critical travel dates that depend on a fast turnaround.
Transfers, extensions, and amendments
H1B status is portable. An H1B holder can change employers without leaving the United States by having the new employer file a new I-129 (a "transfer," though USCIS does not use that term officially). The beneficiary can start work for the new employer as soon as USCIS receipt is issued, under AC21 portability, even before the new I-129 is approved.
Extensions are filed before the current I-797 expires. The standard initial H1B is 3 years; extensions can take the total time to 6 years. Beyond 6 years, AC21 extensions are available when the employment-based green card process is sufficiently advanced. Specifically:
- Section 104(c) extensions: 3-year H1B extensions available when an I-140 is approved but priority date is not current. Renewable indefinitely until the priority date becomes current.
- Section 106(a) extensions: 1-year H1B extensions available when PERM or I-140 has been filed more than 365 days before the extension request. Renewable annually.
Amendments are required when there is a material change to the H1B employment: change of worksite outside the LCA-covered area, significant change of duties, change of employer through merger or acquisition. The 9th Circuit's Matter of Simeio Solutions decision established that a worksite change to a new metropolitan statistical area requires a new LCA and an I-129 amendment, filed before the change. Failing to amend can be treated as unauthorized employment.
Returning to the consulate for re-stamping is required only when the beneficiary needs to travel internationally and the existing visa stamp has expired. The underlying H1B status in the United States is not affected by the stamp expiration; only the ability to re-enter is. Many H1B holders stamp once at initial issuance and again at the first renewal trip outside the US.
Common pitfalls and RFEs
Several patterns drive most H1B RFEs and denials:
- Weak specialty occupation evidence: USCIS asks for evidence the role requires a bachelor's degree in a specific specialty. Generic IT roles, marketing roles, and operations roles often draw RFEs asking for stronger documentation of specialty.
- Generic degree requirements: a job posting that accepts "a bachelor's degree in business, computer science, engineering, or related field" undermines the specialty argument. Stronger postings name a narrow specialty (computer science or directly related quantitative field).
- Third-party placement scrutiny: consulting companies placing beneficiaries at end-client sites must prove the petitioning employer retains the right to control the beneficiary's work. Project documentation, end-client letters, and timesheet evidence help.
- Wage level inconsistency: if the LCA wage is Level 1 (entry-level) but the job duties described are senior-level, USCIS RFEs to reconcile. Match the wage level to the actual responsibilities.
- Beneficiary qualifications: foreign degrees need credentials evaluations. Three-year bachelor's degrees from some countries may need a combination of education and experience to equate to a US 4-year bachelor's.
- Employer financial stability: USCIS may ask for evidence the employer can pay the offered wage. Tax returns, financial statements, and payroll records help.
- Photo failures at consular stamping: DS-160 photo issues delay the case at the consulate even after I-129 is approved. Validate the photo before upload. See our US visa photo page.
Premium processing speeds the timeline but does not change the outcome. A weak case with premium processing gets a faster RFE or denial, not a faster approval.
Photo requirements at a glance
H1B stamping at the consulate requires a DS-160 digital photo upload (typically a 600x600 JPEG meeting State Department specifications) and a printed 2x2 inch backup on the interview day. The photo must be recent and match the appearance you present at the interview, including current facial hair and hairstyle. Validate the file before upload with our photo validator and review the full US visa photo rules before printing. Failed photo upload silently blocks DS-160 and triggers booking delays.
How to navigate the H1B process as an applicant
- Confirm your sponsor. Find a US employer willing to file H1B and confirm your role qualifies as a specialty occupation.
- Register in the lottery. Your employer registers you electronically with USCIS during the March window.
- Wait for selection. USCIS selects registrations through a random lottery and notifies sponsoring employers.
- Employer files I-129. If selected, your employer files Form I-129 with the LCA, evidence of role qualification, and your credentials.
- Wait for approval or RFE. USCIS either approves, requests evidence, or denies. Premium processing speeds this to 15 business days.
- Schedule consular stamping. After approval, file DS-160, upload a compliant photo, pay MRV, and book biometrics plus interview.
- Attend the interview. Bring I-797 approval, DS-160 confirmation, MRV receipt, photo, employer letter, and educational credentials.
