A valid passport is needed when entering Costa Rica. The customs officer stamps your passport and writes a number in the stamp. This is your tourist visa; the number states the amount of days that you are allowed to stay in Costa Rica. This will be maximum 90 days. It is strongly advised to already have your return flight ticket at hand, so that you can proof your departure date. Costa Rica customs is trying to reduce the amount of ‘perpetual tourists’, which is also the reason why in some case they ask for a valid credit card or USD 500, – in cash. However, this rarely happens when entering Costa Rica by plane (it is more likely when entering Costa Rica over land).
