Cultural Tip
In Brazil and most Portuguese‑speaking countries, the customs declaration is often handed out on the plane before landing. Some airports also have kiosks or a dedicated counter where you can fill it out. Remember to keep the completed form handy, as officials may ask to see it before you pass through the customs gate.
