A travel clearance letter is a certified legal document signed by Swiss counsel confirming that, based on a comprehensive audit, no Interpol or SIS II alert exists in your name. It is the premium deliverable for high-net-worth travellers who need documented certainty before a flight. The letter carries the authority of Swiss legal counsel and is accepted by border authorities, banks, and visa officers as definitive.

The travel clearance letter is the culmination of the pre-travel audit process. It is the document that a traveller can carry (digitally or physically) and rely on — not as a guarantee against future alerts, but as certified confirmation that, as of the date of the audit, no alert exists across the queried systems. For high-net-worth travellers, corporate executives, and anyone whose travel has high stakes, the letter is the difference between certainty and guesswork.

What the Travel Clearance Letter Contains

The letter is signed by Swiss counsel and includes:

  1. Cover letter from counsel: Confirming that a comprehensive audit was conducted, the databases queried, the date of the audit, and the results.
  2. CCF response (or certified summary): Confirming whether any Interpol data exists in your name.
  3. SIRENE response: Confirming whether any SIS II alert exists.
  4. SLTD verification: Confirming that no erroneous passport flag is active.
  5. Legal analysis: Assessing the transit-airport database integration on your planned route and the client's individual risk profile.

Critical Warning for Travelers

The travel clearance letter reflects the database state at the time of the audit. If a diffusion is circulated after the audit but before travel, the letter is no longer current. Time the audit within 2-4 weeks of the flight, and if you have ongoing risk, file an urgent update check before flying.

What Makes the Letter Authoritative

The authority of the travel clearance letter derives from three sources. First, it is signed by Swiss counsel bound by Article 321 of the Swiss Criminal Code, which imposes absolute professional secrecy on the attorney-client relationship. This means the letter is a privileged communication, and the audit underlying it was conducted under privilege. Second, the letter is based on a comprehensive audit that queries the same databases border terminals query — Interpol (via CCF), SIS II (via SIRENE), and SLTD. Third, the letter cites the Commission's written response (or a certified summary), which is the most authoritative confirmation of Interpol status available.

No commercial service, public search, or self-certification can match this combination. A commercial "background check" is not privileged and does not query private Interpol data. A public search is not comprehensive. A self-certification is not independent. The travel clearance letter, by contrast, is a privileged, comprehensive, and independent confirmation of clean status, signed by counsel whose professional reputation stands behind it.

When to Use the Letter

The letter is used in several practical contexts. For travel, it provides documented certainty that no alert exists as of the audit date — not a guarantee against future alerts, but a certified snapshot that the traveller can rely on. For banking, it can be presented to a compliance officer to resolve a false-positive freeze, because the bank accepts the Commission's certification over its own screening software. For visa applications, it can be included as supporting documentation where the immigration authority requires confirmation of clean international status. For corporate transactions, it provides due-diligence assurance to counterparties.

The letter must be timed correctly. It reflects the database state at the time of the audit, and if a diffusion is circulated after the audit but before the travel or banking decision, the letter is no longer current. For this reason, we advise clients to time the audit within 2-4 weeks of the planned use, and to file an urgent update check if the underlying risk persists or changes.

The Privilege Protection of the Clearance Packet

The clearance packet is protected by Article 321 of the Swiss Criminal Code, which means that the audit underlying the packet, the counsel's work product, and the communications between counsel and client are all professionally secret. This privilege protection is what distinguishes the clearance packet from a commercial background check or a public search result. The packet is not merely a collection of data; it is a privileged legal document, and its disclosure to third parties is controlled by the client.

The privilege protection has practical consequences. The client can present the packet to a bank's compliance officer, a visa officer, or a border authority, without waiving the privilege that protects the underlying work. The recipient accepts the packet as a certified document, not as a waiver of confidentiality. This is particularly important for clients who need to demonstrate clean status without disclosing the underlying legal concerns that prompted the audit. The privilege protects both the content and the context of the audit.

What to Do in Practice: Secure Your Clearance

A travel clearance letter signed by Swiss counsel is the premium deliverable for documented travel certainty. It confirms, based on a comprehensive audit, that no alert exists across the queried systems. For high-stakes travel, the letter is the document you rely on — not a public search, not a commercial service, and not a guess.

If you suspect your name is on an international watchlist or have an upcoming flight, do not leave your freedom to chance at a passport terminal. A confidential Interpol lookup or a comprehensive Pre-Travel Legal Check filed through Swiss legal counsel secures absolute clarity within days.
