Customs regulations include restrictions on the import and export of live animals, weapons and drugs. You can bring in 1L of liquor, 200 cigarettes and 50 cigars. Those bringing in large amounts of medical supplies independently have frequently been faced with large importation fees.
All foreign visitors must have a valid passport to enter Haiti. Be sure you have room for both entry and exit stamps, and retain the green entry card you’re given on arrival, as you may be asked for this on departure.
Generally not required for stays up to 90 days.
Unless you’re a citizen of the DR, Colombia or Panama, no visa is needed to visit Haiti, just a valid passport and a return or onward ticket. Your entry stamp entitles you to stay for up to 90 days.
If you wish to stay longer, you must apply for a visitor/resident visa at your nearest embassy before you travel. This process can take several months, involving letters of support from your employer or a Haitian resident.
