Majority of visas are stickers placed into your passport. To be able to do that the embassy will require original passport, which they will keep for the whole duration of the application process. For that reason you will need to send the actual passport to us to apply for the visa.
The only exception to this rule are eVisas which are issued electronically with just a copy/ scan of your passport. This option, however, is only available for a small number of countries. Please check the visa options to see if eVisas are available to the country you are travelling to.
