• Bring supporting documentation to the border
• CBP officer makes immediate decision

• Obtain a TN visa stamp in passport
• Schedule a visa interview
• Present supporting documentation at interview
• Once visa is issued, enter the U.S. and begin working
• Alternatively, apply for change of status if already in the U.S.

FAQFrequently Asked Questions

Q:Can I apply for a green card while on TN status?

A: This is complicated. TN requires 'nonimmigrant intent' (temporary stay), while green cards require immigrant intent. Pursuing a green card while on TN can be risky and may result in denial of TN extensions or re-entry.

Q:What happens if my TN application is denied at the border?

A: If denied, you cannot enter the U.S. for work. You can reapply with better documentation or address the reason for denial. Canadians can try a different port of entry.

Q:Can I work for multiple employers on TN status?

A: Each employer requires separate TN authorization. You can hold multiple TN statuses simultaneously, but each must be individually approved.

Q:Is a degree always required for TN status?

A: Most TN professions require a bachelor's degree. Some (like Management Consultant) may accept alternative qualifications with extensive experience.

Q:How long does TN renewal take?

A: For Canadians, renewal at the border is immediate. For Mexicans, consular processing takes 1-4 weeks. USCIS extensions from within the U.S. take several months.

Q:Can I switch employers while on TN?

A: Yes, but you need new TN authorization for the new employer. You cannot work for the new employer until the new TN is approved.
