Most types of visits require an Indian traveler to obtain a visa to Ecuador beforehand, often a tourist visa, a business visa, or a transit visa. To make sure that your application and arrival processes are smooth, the following documents should be ready beforehand:

1. Legal Indian passport with a minimum of six months validity on the date of entry into Ecuador.
2. Blank pages in your passport where you have to stamp in or stamp out and the immigration marks.
3. Confirmed return or onward travelling ticket, indicating how you intend to leave within the allowable stay.
4. Evidence of accommodation, i.e., a hotel booking confirmation or invitation by your host in Ecuador.
5. Evidence of the necessary funds (bank statements within the past three months, credit cards, or sponsorship letter) to finance your stay.
6. Finished visa application form (Ecuadorian e-visa system or embassy web site).
7. Passport size, photos according to the requirements (white background, fresh photo, Ecuadorian).
8. It is highly advised and required with certain types of visas to have travel insurance that covers medical emergencies.
9. Other documents: a letter of invitation, letter of the employer (business visa), a letter of enrolment (student visa), or details of transit to onward travel, depending on the reason for your visit.
10. Payment of visa fee which is normally in USD or online when applying e-visa.

Important to note: The visa requirement varies depending on whether the application is done at an embassy or through the online e-visa system of Ecuador. Before applying, it is always advisable to visit the official Ecuadorian government page or the consulate.
