In addition to the "guarantor" and the proof of local income, you have to go to your local tax office (depending on where you live) in person, stay on line for some time and finally deal with the people on the other side of the river who, in 95% of the cases, don't speak English or pretend to not speak English; then, they will ask a lot of completely illogical questions that are consistent in the sense that any answer you provide will not satisfy them. Finally, if there is a happy ending, you'll have the ΑΦΜ that will allow you to own one more CC that you'll have to pay an annual fee for and which be useful for what? Free advice from a medic: forget it!
