I'm a 35 yrs old nigerian,married to a greek citizen,what are the requirement for the greek passport?

If you reside in Greece with the Greek citizen, then it is the normal process of naturalization [note: it is expedited if you have a child].

If you do not reside in Greece, then there is no path to Greek citizenship solely by being married to a citizen.

Hi, kingemy!

You might also want to put the two words, Greek Passport into the search function of this site to read the information where this has been discussed a number of times.

Thanks!
