This guide is designed to answer one high-intent question for American readers, then connect that answer to the next owner page or support page needed for a real decision.
Most American readers start by asking what the legal requirement is, but the route-level requirement is only one layer. Real-world preparation also includes source-of-funds proof, identity and civil-status documentation, translations, apostilles, family logic, and banking readiness.
That makes the requirements page a bridge between eligibility and process rather than a standalone legal summary.
These links sit beside the core content so Google and readers can move through the adjacent planning, tax, process, and family pages inside the same decision journey.
No. Americans also need to think about source-of-funds proof, banking, documentation, family inclusion, and execution timing.
