Why KoruVest focuses on cross-border decisions
A rule that looks simple can produce a different result when citizenship, visa status, tax residency, or a move across borders enters the picture.
Status changes the answer
We separate immigration status, tax residency, brokerage policy, and account rules instead of treating “non-U.S. citizen” as one category.
Primary sources first
For tax, regulatory, and account rules, we prioritize sources such as the IRS, SEC, FINRA, FDIC, U.S. Treasury, SSA, and official financial-institution documents.
From rule to decision
We use examples, comparisons, and decision points to show what a rule can mean in practice—and where professional advice may still be needed.
