Martin |
| Where There is Tariff Evasion, Tax Fraud is not Far Behind | Tariff fraud often creates ripples beyond customs enforcement — leading directly into income tax fraud cases. This panel dissects real-world patterns where undervaluation, false invoicing, and transshipment schemes in customs filings lead to mismatched income declarations and base erosion on both sides of the U.S.–Mexico border. Experts will explore coordinated enforcement between customs, SAT, and IRS investigators. | Wazirah Allen Jeffrey Adam Neiman Steven Toscher |
| Migration, Expatriation, and Citizenship by Investment: The New Global Landscape with a Trump Gold Card | The panelists will explore and discuss the movement of capital and people across borders: investment-based residency, “golden visa” programs, and citizenship through investment. Covers U.S. expatriation tax rules (§877A), Mexican residency planning, EU programs, and Caribbean models. Emphasis on both immigration (“I”) and emigration/expatriation (“E”) with global fiscal consequences. | Héctor González Legorreta Dr. Kristin Surak Patrick W. Martin |
| Investor Visas, Immigration, and U.S. Tax and Immigration Violations Exposure in an Age of Enforcement | This panel will cover EB-5, E-2, and other investor visas and the tax implications of relocating to the U.S. under the enforcement climate of ICE/IRS.

| Valuation Battles in the U.S. Tax Court (Foreign Assets on the Horizon): Lessons from the Estate of Cecil v/ Commissioner | This presentation will examine in detail the decision in Cecil v. Commissioner, involving Vanderbilt constructed Biltmore Estate -related valuation disputes. Highlights the lead trial counsel and connects valuation controversies to partnerships, offshore companies, and tax-affecting of pass-throughs. Focus on strategic litigation and methodology. | David Aughtry Patrick W. Martin Carsten Hoffmann |
| When Tax Regulations Fail: Federal Courts, Partnerships, and Untimely Assessments – JM Assets, LP v. Commissioner (2025) | This panel will focus on the U.S. Tax Court’s July 2025 decision invalidating partnership regulations, with echoes of Valley Ranch. Discussion of courts striking down IRS/Treasury regulations, implications for statute of limitations, partnership audits, and cross-border entities. | Alejandro Torres Jaime Vasquez Samuel T. Kuzniewski |

| PFIC Planning for Multi-National Families (Not all USC Spouses) | This panel addresses complex PFIC considerations for multinational families, particularly where not all spouses or beneficiaries are U.S. citizens. Panelists will discuss compliance burdens and planning opportunities to avoid punitive outcomes. | Zachary Cruz – Moderator Sebastien Chain Alejandro Diener Anuar Estefan |
| Probate Litigation at the Border: U.S. & Mexico Estate and Probate Issues, Jurisdiction & Enforcement | This panel will explore the complex landscape of cross‑border probate litigation involving estates that span the United States and Mexico. As individuals increasingly own property, reside partly in one country and partly in another, or have heirs or assets on both sides of the border, practitioners face unique jurisdictional, substantive, procedural, and enforcement challenges that do not arise in purely domestic estates. | Luz E. Villegas – Moderator Bernardo Rivadeneyra (Notario #25 Merida) Patrick W. Martin |
