TN, E-3, H-1B1: the country-specific work visas people overlook.

The big picture

Nationality is the key — and it's why these skip the lottery

The regular H-1B is rationed by a lottery because demand far exceeds the annual cap. (We map that machinery in the H-1B guide.) TN, E-3, and H-1B1 are rationed differently. They come from specific trade agreements, so only the citizens or nationals of the partner countries can use them:

• TN — citizens of Canada and Mexico, under the United States–Mexico–Canada Agreement (USMCA).
• E-3 — nationals of Australia, in a specialty occupation.
• H-1B1 — nationals of Chile and Singapore, in a specialty occupation, under the U.S. free-trade agreements with those countries.

Two of these (E-3 and H-1B1) have their own annual caps, but those caps are large relative to demand and have historically gone unfilled — so in practice there is no lottery to win. The TN has no numerical cap at all. The advantage you're buying with your passport is the rationing, not a lower bar: for E-3 and H-1B1 the underlying job standard is the same specialty-occupation standard as the H-1B.

Canada & Mexico

The TN: no cap, no lottery, but citizens only and no self-employment

The TN is the most flexible of the three. There is no annual cap and no lottery, and it can be granted in increments of up to three years with no overall limit on renewals (you re-qualify each time). But it comes with hard edges the State Department spells out:

• Citizens only. You must be a citizen of Canada or Mexico. Permanent residents of Canada and Mexico cannot use the TN.
• A prearranged job with a U.S. employer. Self-employment is not permitted — the TN is for working for an employer in a qualifying USMCA profession.
• How you apply differs by country. A Canadian citizen does not need a visa and can request TN status at a U.S. port of entry. A Mexican citizen must first obtain a TN visa at a U.S. embassy or consulate before traveling.
• Usually a bachelor's degree. With some exceptions, each profession on the USMCA list requires a bachelor's degree as an entry-level requirement, and where a degree is required, experience cannot be substituted for it.

Your spouse and children can come along on TD status for the same period. They may study, but TD dependents may not work in the United States.

Australia

The E-3: an Australians-only specialty-occupation visa with a roomy cap

The E-3 is reserved for nationals of Australia coming to work in a specialty occupation. It looks a lot like the H-1B under the hood — same kind of professional job, same wage protections — but with its own set-aside instead of the general H-1B lottery:

• A certified Labor Condition Application (LCA). The U.S. employer must obtain an approved LCA from the Department of Labor, attesting to pay the higher of the actual wage paid to similar workers or the prevailing wage for the occupation and area — the same wage protection that applies to the H-1B and H-1B1.
• A 10,500 annual cap, principals only. The E-3 classification is limited to 10,500 Australian nationals per fiscal year, and that number counts principal workers only — spouses and children do not count against it. Historically this cap has not been filled, so there is effectively no lottery.
• Renewable in two-year increments. E-3 status is granted in increments of up to two years and is renewable via a new LCA each time, as long as you keep qualifying and maintain the intent to depart when your status ends.

One detail worth verifying for your own situation: the work-authorization rules for E-3 spouses have been changing in recent years, so check the current posture rather than relying on an older summary. We've linked the DOL E-3 program fact sheet below — confirm the live page, which we found temporarily unavailable when this article was checked in June 2026.

Chile & Singapore

The H-1B1: a free-trade cousin of the H-1B, applied for at a consulate

The H-1B1 is the H-1B's free-trade cousin, set up under the U.S. agreements with Chile and Singapore. It is for nationals of Chile and Singapore in a specialty occupation, and its defining feature is how you get it:

• Not petition-based. If you're applying from abroad, this is not a petition-based visa — you apply for the visa directly at the U.S. embassy in Chile or Singapore, rather than waiting on a USCIS petition. (A U.S.-filed petition on Form I-129 comes into play only for an in-country change of status or extension.)
• A 6,800 set-aside. Within the broader H-1B numbers, 6,800 are set aside for the H-1B1 — 1,400 for Chile and 5,400 for Singapore — and these have historically not been reached. Unused H-1B1 numbers roll back into the general H-1B pool for the next year.
• The same LCA and wage rule. Like the H-1B and E-3, the H-1B1 requires a DOL-certified LCA with the higher-of-actual-or-prevailing-wage attestation.

There is a regulatory detail many summaries state about the H-1B1's period of admission, but we could not pin it to a primary regulatory source on this pass, so we're leaving the exact increment to the official pages below rather than printing a number we couldn't verify. Check the State Department and DOL pages for the current period of stay.

The trade-off

What you give up: shorter increments and the intent to go home

Skipping the lottery is not free. The most important difference between these visas and the regular H-1B is nonimmigrant intent. The H-1B is "dual intent" — you can pursue a green card while you hold it without that, by itself, hurting your status. TN, E-3, and H-1B1 are not dual-intent in the same way: each carries an expectation that you intend to depart the United States when your status ends. Openly pursuing a green card can create friction at the consulate or the border in a way it doesn't for the H-1B. That doesn't make a green card impossible — many people do transition — but the path needs more care, and that's a conversation for a licensed immigration attorney, not a blog.

The second trade-off is the calendar. The TN renews in up-to-three-year increments and the E-3 in two-year increments — workable, but they keep you re-qualifying more often than a six-year H-1B run, and the renewals depend on continuing to meet every requirement. If your longer-term aim is permanent residence, it's worth understanding how a work visa connects (or doesn't) to the employment-based green card before you commit to a route.

One protection that does carry over: under a 2016 Department of Homeland Security rule, H-1B1 and principal E-3 workers (along with CW-1 workers) can keep working for up to 240 days while a timely-filed extension of stay is pending — the same continued-employment cushion long available to other categories. That is a distinct rule; don't confuse it with the separate 2024–2025 rules about employment-authorization (EAD) cards.

What's settled vs moving

What's stable, and what you must re-check before you act

The architecture here is stable: nationality-based eligibility (Canada/Mexico for TN, Australia for E-3, Chile/Singapore for H-1B1), the shared specialty-occupation and LCA wage rules for E-3 and H-1B1, the E-3 cap of 10,500 principals, the H-1B1 set-aside of 6,800 (1,400 Chile / 5,400 Singapore), the TN's no-cap/no-self-employment design, and the 2016 240-day continued-employment rule for H-1B1 and principal E-3. Those are statutory or regulatory and steady.

What moves are the numbers, the forms, and the dependent-work rules. Government filing fees roll, so we have deliberately not printed dollar figures here — confirm any fee on the live USCIS fee schedule. Form editions change too: as of June 2026, the current edition of Form I-129 (used for in-U.S. change of status or extension) is 02/27/26, but check the form page before you file. The E-3 spouse work-authorization posture has been shifting with recent EAD rules, so verify it for your own case. And processing times vary — use the official USCIS processing-times tool rather than trusting a quoted number. Check the official source, and check the date on anything you read.
