What documents do you need to enter Ecuador for tourism in 2022?

According to the agreement, those who stay in Ecuador for less than 30 days with ordinary passports for diplomatic, official and business purposes are exempt from visas, but they need to go to the Ecuadorian embassy in China with their passports and issue a letter of proof. If you stay in Ecuador for more than 30 days, you must go through the residence formalities at the Immigration Bureau of the Ministry of Foreign Affairs of Ecuador after entering the country. If you transit to Ecuador through the United States or Mexico, you must apply for a transit visa for that country.
