Mission

US21 publishes vendor-neutral, practical guides for accessing US markets from abroad—focused on requirements, compliance, reporting, and nomad-grade security.

Principles

• Independence: No pay-for-play.
• Evidence-first: We reference primary sources (forms, regulators) where relevant.
• Clarity: Plain English; checklists first.
• Updates: We review cornerstone pages at least quarterly or when a rule changes.

Sources & citations

We prioritize official documentation (IRS, regulators, brokers’ legal pages) and mark uncertainty clearly.
