TN to H1B conversion steps
The TN visa (Trade NAFTA, now Trade USMCA) is a non-immigrant work visa available exclusively to citizens of Canada and Mexico under the USMCA. It allows qualified professionals in designated occupations to work temporarily in the US. Review USCIS H-1B specialty occupation requirements and the DOL prevailing wage database when planning your TN-to-H-1B transition.
TN status is remarkably accessible compared to most US work visas: Canadian citizens can simply present at a US port of entry with a job offer letter and supporting credentials, with same-day approval in most cases. Mexican citizens must first apply for a TN visa at a US consulate before arriving at the border, but the overall process is still significantly faster and cheaper than H1B.
The TN occupation list includes approximately 63 professional categories, such as engineers, accountants, scientists, computer systems analysts, management consultants, pharmacists, and others specifically enumerated in the USMCA Annex 1603.D.1. Notably, the TN occupation list does not cover all professional roles, if your job title isn't on the list, you cannot use TN status for that role.
Canadian and Mexican citizens only. Permanent residents of Canada or Mexico do not qualify for TN status.
Up to 3 years per admission. No statutory limit on renewals, TN can be extended indefinitely in 3-year increments.
TN requires you to maintain non-immigrant intent. Pursuing a green card while on TN creates legal risk and may lead to TN denial at the border.
Both TN and H1B are employer-specific non-immigrant work visas, but they differ significantly in their long-term implications. The most critical difference is immigrant intent: TN requires you to maintain non-immigrant intent (meaning you must intend to return to your home country), while H1B is a "dual intent" visa that explicitly allows you to pursue permanent residency simultaneously. This single distinction is why most TN holders who want to build a long-term career in the US eventually convert to H1B.
| Feature | TN Visa | H1B Visa |
|---|---|---|
| Dual intent allowed | No, cannot intend to immigrate permanently | Yes, inherently allows dual intent |
| Green card path | Very limited; risky if intent shown | Clear pathway via PERM/EB-2/EB-3 |
| Annual cap / lottery | No cap, no lottery, unlimited | 85,000 cap, random lottery selection |
| Employer restriction | Employer-specific (TN tied to employer) | Employer-specific but transferable via I-129 |
| Dependents work authorization | TD visa, no work authorization | H-4 EAD available if I-140 approved |
| Initial period | Up to 3 years, renewable indefinitely | Up to 3 years initial (6 years max, extensions after) |
| Processing | Typically at port of entry, same day | 3–6 months (or 15 days with premium) |
| Cost | $50 USCIS fee + attorney (lower cost) | $5,000–$10,000 total filing fees + attorney |
| Eligible nationalities | Canada and Mexico (USMCA) only | All nationalities |
The TN visa is often described as a great visa for the short term but a poor visa for the long term. The lack of immigrant intent is not just a technical legal point, it has real practical consequences that affect your career options, your family's work authorization, and your long-term security in the United States. Here are the five most important reasons TN holders ultimately convert to H1B:
H1B has explicit dual intent, you can simultaneously hold H1B and pursue a green card through PERM/EB-2/EB-3 without risking your visa status. TN requires you to maintain non-immigrant intent, which legally conflicts with green card applications. USCIS officers at ports of entry can deny TN re-entry if they find evidence of immigrant intent, such as an I-140 approval or a pending I-485.
While both TN and H1B are employer-specific, H1B transfers are more straightforward for the employee. The H1B portability provision (AC-21) lets you start working at a new employer the moment USCIS receives the transfer petition, you don't need to wait for approval. TN portability requires a new TN admission for each employer change, which means another trip to the border or consulate.
Your spouse on TN has TD status with no work authorization. They cannot legally work in the US on TD status. On H1B, once your I-140 immigrant petition is approved, your spouse can apply for H-4 EAD, independent work authorization allowing them to work for any employer. This is a life-changing difference for dual-career households.
H1B can be extended beyond the standard 6-year maximum if your I-140 is approved or your PERM labor certification has been pending for over a year. This provides significantly more long-term security. TN, while indefinitely renewable, requires you to affirmatively demonstrate non-immigrant intent at each renewal, which becomes increasingly difficult if you've been in the US for many years.
Some financial institutions, mortgage lenders, and government contractors prefer or require H1B status over TN because H1B's dual-intent nature and 3-year initial periods provide more planning certainty. H1B sponsorship also signals to employers that you are a long-term investment, which can affect your compensation negotiations and career trajectory.
Converting from TN to H1B is not a single action, it is a 7-step process that plays out over approximately 12 months from initial employer conversations to your first day on H1B status. The timeline is dictated by the H1B lottery calendar, which runs annually from March registration through October 1 start date. Here is the complete process:
Your current employer or a new employer must agree to sponsor your H1B petition. Since you're on TN, you have time, start looking in October/November for April filing. Discuss with your current employer if they are willing to transition you from TN to H1B. Most employers who sponsor TN workers are open to H1B sponsorship, but you need to ask explicitly and give them time to engage their immigration attorneys.
The employer must file a Labor Condition Application (LCA) with the Department of Labor at least 7 business days before H1B filing. The LCA certifies the prevailing wage and working conditions. The LCA must specify the correct wage level (I through IV) and the work location. Processing takes 7–10 business days at dol.gov/FLAG.
USCIS opens H1B electronic registration in early March (typically March 1–20). Your employer submits a registration with your information and pays $215. If selected in the lottery, you proceed to the full petition. You can be registered by multiple employers simultaneously, having backup sponsors improves your chances.
After lottery selection (notified by late March), your employer has until June 30 to file the complete I-129 petition with all supporting documents, fees, and LCA. This includes the specialty occupation evidence, your educational credentials, and the LCA. Premium processing ($2,805) is optional but recommended to get a faster decision and confirmation.
Since you're in the US on TN, Change of Status (COS) is usually the preferred option. This means you don't leave the US, you simply change status from TN to H1B on October 1 when the new fiscal year starts. Consular processing is an alternative: you get the H1B approval, then travel abroad and apply for an H1B visa stamp at a US consulate, and re-enter on H1B status. COS is simpler but consular processing gives you a visa stamp for future travel.
If you filed for Change of Status, you remain on TN status and continue working until your H1B becomes effective on October 1. USCIS will approve your COS petition and issue an I-797 approval notice. Make sure your TN status remains valid throughout this period, if your TN expires before October 1, you may need to renew TN status or travel to Canada/Mexico and re-enter on TN to cover the gap.
On October 1, your status changes from TN to H1B. You can now begin pursuing your green card through PERM/EB-2 or EB-3 pathways. Your spouse may also apply for H-4 status and, once your I-140 is approved, apply for H-4 EAD. Keep your I-797 H1B approval notice safe, it is your primary evidence of H1B status.
Start discussing H1B sponsorship with current or new employer; evaluate whether cap-exempt is an option. Research your employer's H1B sponsorship history at h1bvisajobs.com.
Employer engages immigration attorney, begins LCA preparation. Make sure your specialty occupation documentation is ready.
H1B electronic registration opens (typically March 1–20); $215 per registration. Confirm employer has submitted your registration.
Lottery selection notifications, employers notified if selected. If not selected, plan to renew TN and try again next year.
Selected registrants file full I-129 petition with Change of Status. Premium processing recommended for certainty.
USCIS adjudicates petition (3–6 months regular; 15 business days premium). Watch USCIS case tracker for RFE alerts.
H1B status becomes effective. You are now on H1B and can begin PERM/green card process. Spouse can apply for H-4 status.
One of the most common concerns for TN holders converting to H1B is whether there will be any period where they cannot legally work. The good news is that for Change of Status cases, there is no work gap, you work continuously on TN until October 1, then seamlessly transition to H1B. Here is exactly how the different scenarios play out:
Change of Status (COS), most common
You file the I-129 with COS and your TN is valid through October 1. You work on TN continuously. On October 1, your status automatically changes to H1B per the approved I-797. No gap, no border crossing required. This is the preferred approach for most TN holders.
COS but TN expires before October 1
If your TN expires before October 1 and your H1B COS petition is still pending, you may need to travel to Canada or Mexico and re-enter on a new TN admission to cover the period between TN expiration and October 1. Plan your TN renewal carefully to avoid this scenario.
Consular processing (no COS filed)
If you choose consular processing instead of COS, you must stop working on TN before traveling abroad to obtain the H1B visa stamp, then re-enter on H1B. You can typically plan this timing around October 1 to minimize any gap. Many people travel in late September and re-enter on October 1 in H1B status.
The most important reason the vast majority of long-term TN holders ultimately convert to H1B is the green card. H1B is specifically designed as a "dual intent" visa, meaning USCIS and Congress explicitly recognize that H1B workers may intend to become permanent residents. TN, by contrast, is a non-immigrant visa that explicitly requires you to maintain non-immigrant intent.
Attempting to pursue a green card while on TN status is legally risky. A CBP officer who discovers evidence of immigrant intent, such as a pending I-140 or I-485, at a TN renewal can deny your entry. Even filing an I-140 while on TN is controversial and can be used as evidence of immigrant intent at the border. Once you are on H1B, these concerns disappear entirely.
H1B is significantly more expensive than TN. TN typically costs a Canadian citizen nothing more than a $50 USCIS fee and travel to the port of entry. H1B involves multiple mandatory government fees, optional premium processing, and substantial attorney fees. Here is a complete breakdown of what the conversion costs:
| Fee Item | Amount | Paid By |
|---|---|---|
| H1B Registration Fee | $215 | Employer (usually) |
| I-129 Base Filing Fee | $730 | Employer (required) |
| ACWIA Training Fee (most employers) | $1,500 or $750 (small employer) | Employer (required) |
| Fraud Prevention Fee | $500 | Employer (required) |
| Asylum Program Fee (most employers) | $600 | Employer (required) |
| Premium Processing (optional) | $2,805 | Employer or employee (negotiated) |
| Attorney fees | $3,000–$6,000 | Employer (usually) |
Note: Employers are legally prohibited from requiring H1B employees to pay certain USCIS fees (specifically the ACWIA training fee and fraud prevention fee). Consult with your attorney about what you can and cannot be asked to pay.
Unlike switching from one H1B employer to another, the TN-to-H1B conversion carries a specific set of risks because TN status and H1B have different legal frameworks. Understanding these risks in advance helps you plan mitigations:
Risk: H1B petition is denied (Change of Status)
Mitigation: If your TN is still valid, you revert to TN status and can continue working for your TN-sponsoring employer. You can try again in the next lottery year. If TN has also expired, you must immediately leave the US or change to another valid non-immigrant status.
Risk: H1B receives an RFE (Request for Evidence)
Mitigation: An RFE is not a denial. Respond through your attorney within the deadline (typically 87 days). Common H1B RFEs involve specialty occupation documentation and employer-employee relationship. Your attorney will know how to respond. Continue working on TN during this period.
Risk: Lottery not selected
Mitigation: You remain on TN, no impact. Plan to try again next year. Consider whether your employer or a potential employer qualifies as cap-exempt (university, non-profit research institution), which bypasses the lottery entirely.
Risk: TN expires before H1B COS takes effect
Mitigation: Work with your immigration attorney to renew TN before it expires. Alternatively, travel to Canada or Mexico and re-enter on a new TN admission to bridge the gap to October 1.
Risk: Employer withdraws sponsorship before October 1
Mitigation: If your employer withdraws the H1B petition before October 1, your Change of Status is void. You remain on whatever status you hold (TN if valid). You can seek a new H1B sponsor, but a mid-year H1B petition is only possible through cap-exempt employers. This is a real risk in volatile employment environments.
Not all H1B petitions are subject to the 85,000 annual cap and lottery. Cap-exempt H1B petitions can be filed at any time of year, are approved within normal processing times (or 15 business days with premium), and have no October 1 start date restriction. For TN holders who want to convert to H1B without gambling on the lottery, cap-exempt employment is a powerful alternative.
Cap-exempt employers include: institutions of higher education (universities and colleges), non-profit research organizations affiliated with institutions of higher education, government research organizations, and certain non-profit organizations. Many TN holders in engineering, research, or academic fields have pathways to cap-exempt H1B that they are unaware of.
Any accredited institution of higher education qualifies. This includes community colleges, state universities, private universities, and medical schools. Even part-time or adjunct positions can qualify for cap-exempt H1B sponsorship.
Non-profit research organizations primarily engaged in basic or applied research qualify. Examples include research institutes affiliated with hospitals, think tanks, and independent research labs with 501(c)(3) status.
Federal, state, and local government research entities qualify. Examples include NIH, NIST, national labs (Argonne, Oak Ridge, Lawrence Berkeley), and university-affiliated research facilities.
Non-profit organizations affiliated with qualifying universities or research institutions may also qualify. Affiliation can be through shared governance, ownership, or a formal relationship established in organizing documents.
