Thinking of a vacation to Haiti, Kenya or the Philippines? You may need to revamp your plans. The U.S. State Department reissued warnings against travel to these places this year.

The warning list of about 30 nations considered dangerous for Americans to visit is part of the helpful information at www.travel.state.gov, a site devoted to U.S. travelers abroad. Here you'll find instructions for getting passports and visas; travel tips for women, senior citizens, families, students and people with disabilities; and up-to-date information on health and safety concerns, including terrorist threats and the avian flu.

The department also maintains a Consular Information Sheet for every country, including health conditions, entry regulations, crime and safety information and the location of the U.S. Embassy or Consulate.

U.S. citizens, including children, need to present a passport to re-enter the United States when arriving by air from everywhere in the Western Hemisphere except U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, the Northern Mariana Islands and American Samoa).

U.S. citizens 19 years and older traveling between the United States and Canada, Mexico, Central and South America, the Caribbean and Bermuda by land or sea need to present a valid passport or other documents that prove identity and citizenship, except for U.S. territories. Children need to present only proof of citizenship, such as a birth certificate.

For trip-planning purposes, the Centers for Disease Control and Prevention also maintains a Web site for international travelers with health information about specific destinations, recommended vaccinations and what to do if you suffer an illness or injury abroad: www.cdc.gov/travel.

In addition to the list of tourism offices (or embassies or consulate general offices, in cases where the country does not maintain a tourism office in the United States) below, you can check the Tourism Offices Worldwide Directory at www.towd.com. Since 1994, the directory has offered a pull-down listing of 1,421 tourism offices.
