OSERAN HAHN
Attorneys at Law
Industries & Clients/International Investors

Counsel for Greater China families investing in the Pacific Northwest.

For decades, Oseran Hahn has been a trusted U.S. partner for families and family offices from China, Taiwan, and Hong Kong — from a first home in Bellevue to a multi-property commercial portfolio, a stake in a Washington operating company, or a multi-generational plan that spans the Pacific. Our managing shareholder is Mandarin-fluent, and our team is built for the realities of cross-border investment: time zones, treaties, FIRPTA, CFIUS, FBAR, and the long view a generational family takes when it commits capital to the United States.

The journeyThe teamExperience
The client journey

Wherever you are in the life of the investment.

Most China and Taiwan investors move through the same four chapters — first entry, real estate, operating businesses, and the long-arc stewardship that follows. Pick the chapter you’re working through.

01
▍ 01 / Entry & Structure

The right footing in the U.S. on day one.

How a family from China or Taiwan first enters the U.S. shapes everything that follows — tax treatment, reporting burden, asset protection, and the eventual exit. We sit with the family (often alongside Asia-side counsel and a private banker) to choose the structure that fits the home jurisdiction, the family’s residency picture, and the long view.

  • →Entity selection: LLC, U.S. corp, foreign blocker, trust
  • →EIN, FIRPTA registration, and U.S. tax onboarding
  • →Cross-border banking and escrow introductions
  • →Initial estate-tax exposure analysis for non-resident aliens
  • →Visa & residency overlap with U.S. immigration counsel
02
▍ 02 / Real Estate Investments

From a Bellevue home to a multi-property commercial portfolio.

Real estate is where most China and Taiwan families begin in the Pacific Northwest, and where the portfolio quietly grows over decades. We handle residential closings (Mercer Island, Bellevue, Sammamish, Bothell), commercial and multifamily acquisitions across King and Snohomish counties, 1031 exchanges, and the lender, escrow, and title work that follows. Our team coordinates with Asia-side advisors and translates wire instructions, closing statements, and lender packages in the format the home office actually uses.

  • →Residential acquisitions and second-home closings
  • →Commercial, multifamily, and mixed-use acquisitions
  • →1031 exchanges and portfolio recycling
  • →Acquisition financing & cross-border lender coordination
  • →Property-management, leasing, and landlord counsel
03
▍ 03 / Business Acquisitions & Joint Ventures

Buying U.S. operating companies, and partnering with U.S. founders.

Beyond real estate, families and corporate investors from Greater China increasingly acquire or take meaningful stakes in U.S. operating businesses — manufacturing, distribution, technology, and services. We handle the diligence, the purchase agreement, CFIUS analysis where it applies, employment and IP integration, and the joint-venture documentation when the family prefers to partner with a U.S. operator rather than buy outright.

  • →Acquisitions of U.S. operating businesses
  • →Minority investments and joint ventures with U.S. partners
  • →CFIUS analysis and filings
  • →Employment, IP, and tech-transfer integration
  • →Cross-border M&A in coordination with Asia-side counsel
04
▍ 04 / Stewardship & Generational Transfer

Compliance, reporting, and passing the U.S. assets to the next generation.

Once assets are in place, the work shifts to keeping them sound and eventually passing them on. Annual U.S. tax filings, FBAR, FATCA, and the Corporate Transparency Act beneficial-ownership reports are non-negotiable. Beyond compliance, we help families plan the long arc — pre-immigration planning for the next generation, transfer of U.S. assets to U.S.-resident children, and the FIRPTA-aware sale when an asset has done its job.

  • →U.S. tax filings (1040-NR, 1120-F, 1065) coordination
  • →FBAR, FATCA, and CTA beneficial-ownership reporting
  • →Repatriation, distribution, and withholding planning
  • →Pre-immigration planning for relocating family members
  • →Generational transfer of U.S. real-estate and business interests
