Some visas require a fee. The process may take several weeks for each visa, so apply well in advance. If the country you plan to visit requires a tourist card, you can obtain one from that country's embassy or consulate, from an airline serving the country, or at the port of entry. For some tourist cards, a fee is required. Check entry requirements while you are planning your trip.
Some countries require only proof of U.S. citizenship to enter and depart the country.
Check with the appropriate embassy or consulate for exact requirements before departure. Leave at home all unnecessary credit cards, expensive jewelry, or irreplaceable family objects. Don't pack too much or your bag will be too heavy to manage. Read the Travel Health articles posted on this website, for what to take for your health needs. Make photocopies of your airline ticket, passport identification page, driver's license, and the credit cards you take with you.
