The form can be filled out in person or via email, fax or e-mail. In either case you will be asked to provide proof of your identity, a recent photograph and a copy of your passport. You'll also be required to declare in which you reside and any other location which you would love to go to Greece. A PLF is a legal document that proves you have lawfully traveled to Greece and received the essential travel documents.
