Can I apply for a two-month e-visa online and later extend it for an additional month while having a return flight beyond that period?

You can apply for a two-month e-visa online and then extend it for an additional month. It's advisable to apply with your current onward travel plans, as the embassy may contact you for further flight information if necessary. Some consulates require proof of onward travel within the initial visa validity, so there is a risk that your application could be affected by your return flight. To avoid potential issues, consider booking your return flight for 90 days and purchasing a low-cost separate flight to a nearby country within the 60-day period.
