Swiss extradition to the United States is Federal Office of Justice territory under the 1990 treaty that entered into force around 1997 and the Federal Act on International Mutual Assistance in Criminal Matters - IMAC. Swiss nationals are not extradited without their written consent. IMAC fiscal carve-outs can block pure tax cases. White-collar, banking, and tax-adjacent fraud packages into SDNY remain the classic Geneva and Zurich corridor. Spodek Law Group P.C. maps consent and fiscal limits before anyone treats a Swiss passport as decorative. Risk-free consultation. Call 212 300 5196.
FOJ-centric process - Bern decides, not a casual border chat.
Swiss extradition runs through the Federal Office of Justice under IMAC and the bilateral treaty. Cantonal custody may hold you, but surrender architecture is federal. Treating Switzerland like a quick transfer point misses FOJ procedure, dual-criminality review, and human-rights filters that still delay defective US dossiers when counsel force them early.
Swiss nationals need written consent - that is a real bar.
Switzerland does not extradite its nationals without their written consent. That is not a negotiable embassy favor. For citizens, strategy turns on whether consent is rational after counsel maps outcomes - or catastrophic if it abandons winning fiscal or dual-criminality paths. Non-nationals face a different file entirely. Fix passport status before anyone markets Swiss cooperation myths.
IMAC fiscal carve-outs - pure tax fights are live.
IMAC limits extradition for certain fiscal offenses standing alone. US prosecutors often wrap tax conduct inside fraud, conspiracy, or banking narratives to escape carve-outs. Those wrappers still need Swiss offense matching. We separate pure tax exposure from extraditable fraud theories while preparing the American white-collar case that expects you after Zurich.
1990 treaty, ~1997 entry into force, and modern white-collar packages.
The 1990 bilateral instrument, effective around 1997, frames contemporary cooperation with documentation and specialty rules that matter in banking corridors. Summaries travel well in press releases and poorly when FOJ counsel force precision. Creative market and wire-fraud theories fail when Swiss analogs do not line up. Every translated affidavit is a fight document.
Banking pressure makes statements common - refuse the script.
High-net-worth custody settings generate voluntary-return and cooperation scripts. Statements to Swiss authorities or visiting US personnel become SDNY exhibits. Consent to national surrender ends fiscal and dual-criminality leverage in one signature. You need Swiss counsel for FOJ practice and US counsel for the financial district indictment. Spodek Law Group P.C. coordinates both under one privilege umbrella.
