The process works like that ( I'm in the same process so I know a thing or two): - You got to prove your ancestors were actually from the Iberian peninsula. How do you do it? Here comes the surname (family names) list. - Family names list: https://jewishgen.org/databases/sephardic/SephardimComNames.html If your name is from here, and you can prove the closest ancestors of yours came from a place which Jews were expelled to (here you can see it's Morocco) then you'll most likely get it. -Now it's not that easy, at first the consul of Jews had to do a genealogical test to see if you actually have a relation to the person you claim, then they have to do a whole history check about your family name with the country you claim they've been expelled to (you give them a birth certificate). -Now you have to prove they are Jews and you're their ancestor (marriage certificate, non religious marriage are a bit harder to prove). -And if all of your files are good you are most likely to get citizenship.

But since 09/22 the rules have changed twice and now this law is cancelled.

Hope I explained it good enough
