Every March, U.S. employers get a narrow window to file for the visa that lets them hire foreign engineers, doctors, professors, and software developers. The process costs thousands of dollars per worker, takes months of planning, and comes with roughly a one-in-four chance of even getting a slot. Then it happens all over again the next year.

The H-1B is the country's main work visa for college-educated professionals in "specialty occupations" — jobs that normally require at least a bachelor's degree in a specific field. Congress caps it at 65,000 visas per year, plus 20,000 more for people who earned a master's degree or higher from a U.S. university. Those numbers have not changed since 2004. Demand has.

For employers, the H-1B is not a single form. It is a sequence of deadlines, fees, and legal obligations that can stretch past a full year before a new employee ever sits at a desk. Miss one step and the entire effort resets to next year. Here is how the system actually works, what it costs, and where companies most often stumble.

The Annual Clock: Registration, Filing, and the October Start

The modern H-1B process begins with online registration, not a full application. U.S. Citizenship and Immigration Services (USCIS) opens a registration window each March, typically running about two to three weeks. Employers pay a $215 fee per beneficiary just to enter the lottery. No supporting documents, no proof of the job offer, no evidence of the worker's qualifications — just names in a digital hat.

If more registrations come in than visas available, USCIS runs a random selection. It has run one every year since the registration system launched. In recent years, registrations have topped 400,000 to 780,000 for those 85,000 slots, though the numbers swing with economic conditions and how many people file multiple entries through different employers.

Selected employers then have at least 90 days to file the full I-129 petition, the actual application. That packet includes the Labor Condition Application (LCA) certified by the Department of Labor, proof the job qualifies as a specialty occupation, and evidence the worker holds the required degree. Premium processing — now $2,805 — gets a decision in 15 business days instead of the standard months-long wait.

Here is the part that catches people off guard: approval does not mean the worker can start. For most new H-1B hires, the visa does not take effect until October 1, the start of the federal fiscal year. Someone selected in March might not begin work until October — a seven-month gap. Employers who need the person sooner have to look at other visa categories or wait.

Roughly one in four registrations has been selected in a typical year. The rest of those employers start over with zero.

What the H-1B Actually Costs in 2025

The sticker price of an H-1B filing runs from about $2,000 to more than $10,000 per worker, depending on the employer's size, whether premium processing is used, and whether an immigration attorney is involved. Here is where the money goes.

  • Registration fee: $215 per beneficiary, paid every year you enter the lottery.
  • I-129 base filing fee: $780 for employers with 25 or fewer full-time employees, $1,385 for larger employers (as of the latest USCIS fee schedule).
  • American Competitiveness and Workforce Improvement Act (ACWIA) fee: $750 for small employers, $1,500 for employers with 26 or more employees.
  • Fraud Prevention and Detection fee: $500, required for most initial petitions.
  • Public Law 114-113 fee: $4,000 for employers with 50 or more employees if more than half of their workforce holds H-1B or L-1 status.
  • Premium processing: $2,805 for a 15-business-day decision.
  • Attorney fees: commonly $1,500 to $4,000, sometimes more for complex cases.

Two rules matter here. First, the employer must pay the filing and ACWIA fees — you cannot legally pass those to the worker. Second, premium processing and attorney fees are negotiable, but shifting mandatory government fees onto the employee is a violation that can trigger penalties.

Multiply it out. A mid-size tech company hiring 20 H-1B workers in a year could spend well over $100,000 before a single offer letter is signed, and that assumes every registration gets picked. Many do not.

Why So Many Registrations Get Rejected or Denied

Getting selected in the lottery is only the first gate. USCIS denies a meaningful share of petitions, and the reasons are predictable.

The most common problem is the "specialty occupation" test. The job must require a bachelor's degree in a specific field, and the employer has to prove it. A "marketing manager" role with no degree requirement will not pass. A "software engineer" role that lists a computer science degree as a hard requirement usually will. Vague job descriptions invite scrutiny.

Another frequent failure: the employer-worker relationship. USCIS wants to see that the company controls the worker's day-to-day duties. Staffing firms and consulting shops that place workers at client sites face extra documentation demands, and denials in that category have run high.

Then there is the wage question. The LCA requires employers to pay the higher of the actual wage or the prevailing wage for the occupation in that location. Paying below market is not just a denial risk — it can draw Department of Labor investigations and back-wage penalties.

Finally, timing. Filing the I-129 late, missing a signature, or submitting an expired LCA will get a petition rejected outright, refunded, and returned. With a 90-day filing window, a two-week delay can be fatal.

What Employers Should Do Before the Next Registration Window

Companies that treat the H-1B as a last-minute scramble lose. The ones that succeed build the process into their annual hiring calendar. A few practical moves make a real difference.

Start in the fall, not the spring. Identify the roles you will need to fill, confirm they qualify as specialty occupations, and get your job descriptions reviewed by counsel months before registration opens. You cannot register a job that does not meet the standard.

Budget the full cost, not the filing fee. Build a per-hire number that includes registration, government fees, premium processing, and attorney time. For a large employer using premium processing, plan on $8,000 to $10,000 per worker.

Consider the cap-exempt route. Universities, nonprofit research institutions, and affiliated nonprofits can file H-1B petitions year-round with no lottery and no cap. If your company partners with one, that relationship may open a path.

Have a plan B for the worker. If the registration is not selected, options include the O-1 visa for people with extraordinary ability, the L-1 for intracompany transfers, TN status for Canadian and Mexican professionals, or waiting for next year's lottery. Some workers can extend their student OPT status or move to a cap-exempt employer temporarily.

Keep records for the whole employment period. The LCA comes with public access file requirements and posting obligations. The Department of Labor can audit years later. Sloppy paperwork is a compliance risk long after the visa is approved.

What Changes and What Does Not

The H-1B program has been the subject of reform proposals for two decades. Fee schedules get updated. The registration system gets tweaked. Enforcement priorities shift with each administration. What has not changed is the 85,000 cap, the March registration window, and the October start date.

That stability cuts both ways. Employers can plan around a predictable calendar. They also cannot count on the rules loosening enough to make the lottery less of a gamble. For a U.S. company that needs specialized talent and cannot find it domestically, the H-1B remains the primary tool — expensive, uncertain, and slow, but still the main road.

The employers who come out ahead treat it that way: a long-term pipeline to manage, not a form to file. They build the timeline into their hiring plans, budget the real costs, and keep a backup option ready for the years the lottery does not go their way. That discipline is the difference between filling a critical role and losing the candidate to a competitor — or to another country.
