When do I need to apply for a visa if I discover I need one? To account for the typical processing period, applicants should submit their forms as long in advance of their intended trip date as possible. An application for a visa can often be submitted up to 90 days before a traveller is scheduled to depart.
Even though your visa is still valid, you will need to apply for a new one if you want to enter the country again. The number of times you can enter a nation is not limited if you have a multiple-entry visa. Certain visas only allow for two or three entries, so you'll need to use caution.
This process is necessary since many authorities will review your visa application
