Once your e-Visa is approved, it will be valid for a single entry into Egypt within the specified 90-day period. This means that you have 90 days from the date of issue to enter Egypt. Once you have entered the country, you can stay for a maximum duration of 30 days.
It's worth noting that the e-Visa is only valid for tourism purposes and does not grant you permission to work or engage in any form of employment in Egypt. If you plan on working or studying in Egypt, you will need to apply for the appropriate visa through the Egyptian embassy or consulate.
Remember, visa regulations can change, so it's always a good idea to stay informed and check for any updates before planning your trip to Egypt. The official Egyptian embassy in Finland will have the most accurate and up-to-date information regarding visa requirements and validity.
