While it is advisable to plan ahead and apply well in time, do keep in mind that the earliest that you can apply is 90 days or 3 months prior to the expected day of your departure.
It is recommended that the request be lodged at the earliest possible date and at least 16 calendar days before the planned visit. Please note that applications cannot be submitted more than six months before the date of commencement of the planned tour.
The holder of a valid visa can submit an application for a new visa before the current visa expires
