Keep in mind that there are no requirements to have special skills, level of education, or work in a specific sector. Estonian officials also don't care about your country of origin. The main criteria are income level and approval of your digital "nomadness" — this measure allows Estonia to attract strictly well-paid talented workers and minimize an unsavory migration.
Matching these criteria, feel free to fill in the DNV application form online on the governmental website
. After that, you need to print and sign the application, collect all required documents, and visit the nearest Estonian embassy or consulate personally to provide them with all the necessary information and papers. You can find the list of documents here
(item 9). When your application is successful and your visa is ready, you will be notified by an embassy. During the second visit to the embassy, you'll verify your identity and freely pick your visa up. Also, remember that you can apply for DNV right in Estonia at a local Police and Border Guard office. So if you have no Estonian embassy in your country or it's complicated to visit one, you can apply for DNV from Estonia, using a common tourist visa.
