Travelers should avoid bringing meat or raw fruit or vegetables into the U.S., but may bring cooked nonmeats, such as bread. The U.S. Customs process is straightforward. Most articles that are prohibited or restricted in any other country are prohibited or restricted in the USA. The only rule that is unique to America is that it is generally prohibited to bring in goods made in countries on which the U.S. has imposed economic sanctions, e.g., Cuba, Iran, North Korea, and Myanmar (Burma). Besides their personal effects which will go home with them, visitors are allowed to import $200 of merchandise duty free, including 1 liter of alcohol (21 and older only) and 1 carton of cigarettes. If you are bringing in more than US$10,000 or its equivalent, you must declare it on your customs form and you will be given a special form to fill out. At immigration, the officer usually puts some sort of a tick mark on your customs declaration form to alert the customs officer of any need to search you or your luggage. After you are admitted into the U.S. and you retrieve your bags, you will proceed to the secondary inspection area (customs checkpoint). Hand your customs declaration to the officer. Most of the time, the officer will point you to the exit and that will be it. The officer may ask you some routine questions and then let you go. The officer may refer you to the x-ray to have your bags inspected, or may refer you for a manual search of your bags. Customs has the right to search your person and your bags, but any search more intrusive than a bag search is rare, and is usually indicated only if some sort of probable cause has been established through questioning or during the bag search to suggest suspicious activity.
