The rules vary from country to country.
You can't claim citizenship by a ancestor. My family came from Londonderry Ireland in the 1600's to the Virginia colonies, but I can't get Irish citizenship from Ireland because they were Irish. You have to be born in a country to claim citizenship or have a parent from a country to claim duel citizenship.
You did not claim Roman citizenship. if you were born in Rome and a freeman, you were automatically a Roman citizen. There were non-Romans who obtained Roman citizenship. However, they did not claim it. During the Roman Republic the senate granted citizenship. During the period of rule by emperors it was the emperor who granted it. It was the Romans who chose who they wanted to grant citizenship to. Therefore, non-Romans did not claim it.
i want to know this too! it sounds like you need a parentwho is a french citizen, and that grandparents don't do it...
your existing legal resident status would not be affected by anybody , you can claim citizenship when you have the right to do so.
you need to listen to have citizenship
Contact your nearest German consulate. Citizenship questions are often complex.
You need to apply yourself but using them as character witnesses can help. You need to prove something horrible will happen to you if deported.
If there was a visa denial you cannot argue about the denial itself- you must attack the false claim. A false claim of U.S. citizenship is a permanent bar to immigrating to the U.S.- there are NO waivers. The only thing a person can argue is that they never made a false claim to citizenship, or that it was timely retracted, and finely, that the person had a valid belief he/she was a citizen (but there are certain requirements for this defense).
Bulgaria and Israel might recognize dual-citizenship for you but if you were born in the US (or became a naturalized citizen) - you cannot claim dual citizenship in this country.
No, this isn't enough to claim French citizenship. Your father or mother have to be French to claim French nationality in that respect.
Family
If either of your parents was a German citizen at the time of your birth, you have a claim to German citizenship. (Being born in Germany is usually irrelevant and does not confer citizenship).
