H-1B1 vs H-1B: 5 Key Differences for Chilean Professionals

H-1B1 vs H-1B is a comparison worth making before you accept a U.S. offer, because as a Chilean national you qualify for both and the two work very differently. The H-1B1 is a treaty category created under the U.S.-Chile Free Trade Agreement, with 1,400 places reserved each year for Chilean nationals, no lottery, and no petition to USCIS on the consular route.

Eligibility is rarely the problem. Most U.S. hiring managers have never processed an H-1B1 and reach for H-1B lottery language by default, so you'll usually be the one bringing it up. The five differences below are what you need to make that case.

1. No H-1B1 lottery, and a timeline measured in weeks

The H-1B1 Chile visa has 1,400 slots a year, and they have never been filled since the program opened in 2004. You can start in any month, book a consular interview within weeks, and get a visa without waiting for a registration window.

The H-1B cap lottery runs on a fixed calendar: registration for a short window each March, selection in April, earliest start October 1. Accept an offer in May and you could be working by mid-June on the H-1B1. On the H-1B, you'd wait until October the following year, and only if selected.

H-1B selection is also no longer random. A DHS rule effective February 27, 2026 weights the lottery by H-1B wage level, giving a Level 4 registration four entries and a Level 1 registration one. If your offer sits at Level 1 or Level 2, you're carrying the weakest odds in the pool.

2. What the H-1B1 visa costs

The H-1B1 consular route carries no I-129 petition, no ACWIA training fee, and no fraud prevention surcharge. Your employer's only government step is the Labor Condition Application, which has no filing fee.

The applicant side has gotten more expensive. Alongside the machine-readable visa fee, a $250 visa integrity fee now attaches at issuance for most nonimmigrant categories, charged only on approval and applied per person. Bringing a spouse and child adds $500.

That fee hits the consular route and not a stateside change of status, which narrows the H-1B1 cost advantage over H-1B visa costs. Check current amounts on the State Department fee schedule before budgeting.

If you're already in the U.S. and changing status rather than entering on a new visa, your employer files Form I-129 and the USCIS fee schedule applies. Less common, but it's the route that avoids the integrity fee.

3. H-1B1 validity: 18 months on the visa, one year on your stay

Two numbers get confused constantly. The H-1B1 visa can be issued for up to 18 months, but the period of admission on your I-94 is generally one year. Only the second governs how long you can stay.

H-1B1 extensions come in one-year increments with no statutory maximum on how many you can hold. The H-1B visa tops out at six years unless an approved I-140 supports further extensions.

The cost of that flexibility is the renewal. Each extension means a fresh consular interview at Santiago, where the officer re-examines your ties to Chile, and that gets harder after years of continuous U.S. residence, tax filings, and property.

4. H-1B1 spouses cannot work

H-1B1 spouse rules are the weakest part of the visa, and for many people they decide the question. Spouses and unmarried children under 21 receive H-4 dependent status, which allows entry, study, and travel, but no work authorization.

H-1B holders have a route here, because an approved I-140 opens H-4 employment authorization. H-1B1 dependents have no equivalent, and waiting longer doesn't create one.

If your household needs two incomes, this outweighs the H-1B1 speed advantage above. The H-1B is slower and less certain, but it's the route that lets your spouse work.

5. The H-1B1 has no dual intent

H-1B1 dual intent doesn't exist. The visa requires nonimmigrant intent for as long as you hold it, so filing an immigrant petition while on H-1B1 creates real risk at your next renewal, because the consular officer can treat it as evidence you no longer intend to return to Chile.

Most people don't run into this until 12 to 24 months in, when an employer first raises green card sponsorship, by which point the timing question is already overdue.

That switch means an employer-filed I-129 and, unless your employer is cap-exempt, entry into the weighted H-1B lottery described above.
