Opening a U.S. Subsidiary for a Vietnamese Company

May 26, 2026 · 6 min read

Not every company needs a U.S. subsidiary to sell into the U.S. market — plenty of exporters operate successfully through distributors without one. A subsidiary makes sense when a company wants direct control over U.S. operations: holding inventory, hiring staff, building direct customer relationships, or eventually raising U.S.-based capital.

Questions worth answering before committing

  • Do we need direct control over U.S. operations, or would a distributor relationship get us most of what we want with less overhead?
  • What is our funding plan for the U.S. entity, and how does capital move from Vietnam to fund it?
  • Who will operate the U.S. business day to day?
  • What is our realistic timeline to profitability or self-sufficiency for the U.S. entity?

What the process generally involves

  • Entity structure decision with a qualified attorney
  • Formation and EIN registration
  • Banking setup
  • Funding the entity — coordinated with your Vietnam-side and U.S.-side financial and legal advisors
  • Accounting and tax setup
  • Operational buildout — location, staffing, vendors

A subsidiary is a real operational and financial commitment, not just a legal filing. Getting the sequencing and the underlying business case right up front tends to matter more than the formation paperwork itself.
