If prosecutors invited you to tell your side from overseas, you are probably scared - and that is normal. A federal proffer is a short contract for a voluntary interview. After Mezzanatto, waivers of Rule 410 protections became standard. The promise is narrow: typically no direct use of your statements in the government case-in-chief. Everything else around that promise can swallow the benefit - especially when foreign authorities are already sniffing around the same story. Unlike other law firms more focused on their relationship with prosecutors, we owe loyalty to only YOU. We are selective about who we work with - we should only take on clients whom we can help. When you reach out to our law firm, you start with an initial risk-free consultation. You can ask us anything you want. Call 212 300 5196 - attorney on call, 24/7.
What the letter usually protects - and stops protecting.
Most USAO forms let the government use your proffer for leads (derivative use), to impeach you, to rebut defense theories inconsistent with the proffer, at sentencing, and for false-statement prosecutions if you lie. The word immunity in casual conversation is false advertising. Read the carve-outs line by line before you agree to a remote Zoom with an agent.
Foreign spillover is the overseas target problem.
2025 defense commentary keeps repeating a point mills skip: many letters do little or nothing to stop DOJ from sharing what it learns with other US components or foreign partners. Your Queen for a Day in SDNY can become Exhibit A in a home-country file. If your proffer does not address sharing, assume sharing is possible.
Remote proffers from abroad add process risks.
Time zones, recording, who is in the room, interpreter quality, and local law on cooperating with foreign police all matter. Some countries treat informal interviews with US agents as events that trigger local duties. US counsel and local counsel should clear the modality before you speak.
When a proffer can still make sense.
Indictment is likely anyway, a concrete plea path exists if you are truthful, you are prepared to tell the whole truth, and counsel trusts the prosecutor will not be overruled into something uglier. Without those conditions, silence often beats a typed letter that looks friendly.
Limit topics before the session starts.
Older practice sometimes scoped sessions. Today prosecutors push for open books. If certain archives or third-country acts cannot be discussed until a plea exists, counsel must negotiate that before the first question - not mid-session when you are already talking.
Perjury and 1001 are not theoretical.
False statements to federal agents and obstruction theories ride alongside every proffer. Incomplete memory framed as certainty is how people mint new felonies while trying to shrink old ones.
