Before trying to extend, confirm whether your destination country allows eVisa extensions for your visa type. Australia's eVisitor cannot be extended — you must leave and reapply. Sri Lanka's ETA can be extended up to 6 months by visiting the Department of Immigration. Indonesia's eVOA can be extended once for 30 days. The UAE allows one extension per visa. Check official government sources for current rules.
Do not wait until your visa has expired to apply for an extension — overstaying even one day is a violation. Start the extension process at least 2 weeks before your visa expiry date. Some immigration offices in popular tourist destinations have long queues during peak season.
Extension applications typically require: your current valid passport, a completed extension application form (from the immigration office or portal), payment of the extension fee, proof of accommodation for the extended period, evidence of sufficient funds, and sometimes a letter explaining why you need to extend your stay. Check destination-specific requirements.
Depending on the country, extensions are handled either online (some countries have digital extension portals) or in person at the local immigration office. Sri Lanka, for example, requires an in-person visit. Indonesia has an online extension system. Follow the official process precisely — using unofficial "agents" for visa extensions can create legal complications.
In many cases, the simplest way to "renew" an eVisa is to leave the country and reapply from abroad. For short-stay visas (Turkey, USA ESTA, Vietnam), a brief trip to a neighbouring country and immediate reapplication can be cost-effective if the fees are low. However, some countries track frequent border crossings and may question the purpose of your visit.
