To apply for an Estonian work visa from India, you must first obtain a job offer from an employer in Estonia. The employer must register the employment contract with the Estonian Police and Border Guard Board. Once the Estonian employer initiates the process, you will be required to arrange the necessary documents for the work visa, schedule an appointment at the nearest Estonian embassy or consulate, attend the interview, submit your application, documents, and biometrics, and complete the fee payment. The final step would be to wait for the Estonian work visa to be processed, which typically takes around 1-2 months, depending on the type of visa you have applied for.
