TCN Border Stamping Rules
For foreign nationals who apply for a U.S. nonimmigrant visa outside their country of nationality or residence, the process is commonly described as third-country national (TCN) processing. The availability of such appointments is determined by the particular U.S. embassy or consulate and the current Department of State rules.
Automatic Visa Revalidation (AVR) Voiding Rule
Under federal law 22 CFR § 41.112(d), an eligible nonimmigrant with an expired visa may in some circumstances seek readmission after an absence of no more than 30 days solely in Canada, Mexico, or other qualifying contiguous/adjacent territory, using automatic revalidation and a valid Form I-94. The traveler must satisfy all AVR conditions.
Section 221(g) Administrative Processing Risks
If a consular officer issues an INA Section 221(g) refusal, the application may require additional documentation or administrative processing before the consular officer can make a final visa decision. Processing times vary by case.
If you applied for a new visa while abroad, AVR is unavailable. You may need to remain outside the United States or otherwise obtain another lawful basis for admission while the visa case is unresolved. Administrative-processing duration varies by case.
Applying for a new visa while abroad prevents reliance on AVR. To seek admission again, the traveler must qualify under another valid admission basis, which may include a newly issued visa when one is required.
Typical Supporting Documents
Exact document requirements vary by visa category and consular post. Verify the current checklist on the specific U.S. embassy/consulate website before travel.
| Category | Documents Required |
|---|---|
| Host-Country Admission | Carry the documents required by Canada or Mexico for your lawful presence and travel. A Canadian eTA, Mexican FMM, or other document is not a universal U.S. visa-stamping requirement. |
| Petition / Status Evidence | Form I-797 approval notice and other petition/status documents applicable to the visa category. |
| Application & Appointment | DS-160 confirmation page and appointment confirmation, when an appointment is required. |
| Employment / Supporting Evidence | Employment verification, recent pay records, and other evidence requested by the specific consular post. W-2s may be useful but are not a universal requirement for every applicant. |
