H-1B Visa: Lottery, LCA, I-129, and Pitfalls

A cap-subject employer-sponsored visa for specialty occupations requiring a bachelor's degree or higher in a specific field. Annual electronic registration lottery, then a full I-129 petition for selected beneficiaries.

Who qualifies

H-1B requires both a qualifying position and a qualifying beneficiary. The position must be a "specialty occupation" — one that requires theoretical and practical application of a body of highly specialized knowledge and a bachelor's or higher in a specific specialty (or its equivalent) as a minimum for entry. The beneficiary must hold the required degree, or its equivalent through education + experience.

The annual cap is 65,000 for the regular allocation plus 20,000 for those holding a U.S. master's degree or higher. Cap-exempt employers — primarily institutions of higher education, certain research organizations, and nonprofit entities affiliated with universities — can file H-1Bs throughout the year without going through the lottery.

The cap-subject process

For cap-subject H-1Bs, the process is now structured around an electronic registration system administered by USCIS each spring:

Registration window (typically opens early March) — the employer (or attorney on behalf of the employer) creates a USCIS online account and submits a $215 registration for each prospective beneficiary, with basic identifying information.
Lottery selection — USCIS conducts a random selection. Selected registrants receive notice that they may file a full H-1B petition for that beneficiary.
LCA filing — the employer obtains a certified Labor Condition Application from the Department of Labor (Form ETA-9035) before filing the H-1B. The LCA must list the wage, location(s), and other conditions of employment.
I-129 petition — the full petition with supporting documentation must be filed during USCIS's filing window (typically April–June for selected registrations). Premium processing is available.
Visa stamping or change of status — beneficiaries already in the U.S. can have their status changed (effective October 1 if approved before then). Beneficiaries abroad obtain an H-1B visa stamp at a U.S. consulate before traveling.

Common pitfalls that sink otherwise solid cases

Specialty-occupation challengesUSCIS frequently challenges whether a position truly requires a bachelor's degree in a specific specialty — especially for roles like business analyst, marketing manager, or general "engineer" titles where the OOH allows for various educational paths. Building the specialty-occupation case requires clear duties tied to specialized knowledge, with supporting evidence (organizational structure, complexity of work, employer's hiring history for similar roles, prevailing industry practice).

Beneficiary-qualification gapsA beneficiary with a foreign degree needs an evaluation showing U.S. equivalency. A beneficiary with a degree in a different field needs to show how the degree relates to the specialty (often via a credential evaluation that includes work experience as additional education credit). A beneficiary using the experience-only path needs employment letters that meet the three-for-one rule (three years of progressive experience equivalent to one year of education).

LCA wage and location problemsThe LCA wage must equal or exceed the prevailing wage for the position in the geographic area. If the petition lists multiple worksites, each must be on the LCA. If the actual work location differs from the LCA — even a move within the same metro area — the employer may need to file an amended H-1B petition. Wage discrepancies and unfiled-amendment problems are commonly found in LCA-related Department of Labor audits.

Off-site placement and end-client lettersFor H-1Bs where the beneficiary will work at an end-client site (consulting, staffing arrangements), USCIS expects evidence of the end-client relationship — typically a letter from the end client describing the work, duration, and employer's right to control the beneficiary. Petitions without strong end-client documentation in these scenarios face high RFE and denial rates.

How GentleCase manages H-1B cap season

H-1B cap season is the most concentrated workload in immigration practice. A firm filing 30, 50, or 100+ cap petitions has weeks (not months) between lottery selection and the filing window to assemble each beneficiary's full petition — including LCAs, employer letters, beneficiary documents, and supporting evidence.

GentleCase tracks each registration as a separate case file from the moment it's submitted, with status that updates through the cap season: registered → selected → LCA filed → packet assembling → ready to file → filed → receipted → adjudicated. The dashboard shows every active cap case in one view, sortable by status — so the operations lead can see at a glance which 12 cases still need beneficiary documents and which 8 are ready to file.

For the document collection from beneficiaries, the client portal lets each beneficiary upload directly into their case file — passport, degree, transcripts, I-94, prior visas, employment letters. The paralegal verifies or rejects in one click. Petitions that used to require dozens of email threads per beneficiary now have a clean audit trail of what was requested, when it arrived, and who verified it.
