U.S. citizens traveling to Panama by air, road, or sea must present a valid passport that has a remaining validity of at least three months. U.S. citizens attempting to enter without a valid passport will be returned to their point of departure in the U.S. on the next available flight. Panamanian immigration strictly enforces this law.
Tourists must present a return trip ticket or fare back to their home country or next destination upon arrival. Panama also requires a completed international boarding card which is provided by the airline and submitted by the traveler at the point of immigration. In addition to this, no less than five-hundred balboas (USD$500) in cash or its equivalent must be presented as proof of financial solvency. In addition to cash, travelers can show a credit card (with most recent credit card statement), bank reference, letter of employment, or traveler’s checks.
