The Mongolia eVisa Online system allows eligible travellers to apply for a visa before travelling to Mongolia. Applicants can complete the relevant online form, provide passport and travel information, upload supporting documents, and pay the applicable fee electronically. The correct visa category depends on the purpose of the visit and the traveller's nationality. Before starting an application, check the latest eligibility conditions and make sure your passport details are entered exactly as they appear on the document. Once approved, keep a digital and printed copy of the eVisa with your travel documents. Travellers should also check the permitted stay, visa validity, and entry conditions before departure to ensure their plans comply with the approved visa.
