People who served in the French army can apply for French citizenship if they fought for France. Starting from that, your father has first to obtain French citizenship (even if dual with a another nationality). Once that done, you can apply for French nationality (expect that to be slow and uneasy)
no
French passports are for French nationals. If your father holds French citizenship - which is possible from the fact he was born on a French territory, but not automatic - you can in turn apply for French citizenship. It is very unlikely that you could get French citizenship if your father isn't himself French. If he his, that will not be granted automatically either. To size up your chances, contact the French embassy or consulate in your home country.
It is possible only for a person whose father or mother has / had French citizenship, or under special conditions if the applicant is born in France.
Yes, definatly.
Yes you can, you are a citizen because of your parent was but you must register with your closest Trinidad Consulate, to do so you must take your father Trinidad documents as Passport or Birth Cirtificate to prove he was a citizen of Trinidad, then you must also take along your birth certificate and ID to prove he is your father. It's really simple it's even faster if you go to Trinidad with your regular passport then apply there for a Trinidad passport.
I think you would have to do almost the same process as getting a passport. Try the P.O. for the correct paperwork. My guess is that there will be a fee, you'll have to do another photo and turn in the passport you now hold.
Yes, you will be able to obtain the Turkish passport. You might even obtain dual citizenship.
If you have a green card and have lived in the US for at least five years; then apply for American citizenship and become a dual citizen of France and the US. Why giving up your French passport!?* If you are just a French citizen and do not live in the US, thinking about just exchanging the two nationalities with eachother, the answers is no.
This depends on what country he is coming from. He may need to apply for a visa.
I need to apply for a passport.
Usually when you have the passport at hand. It is stipulated in the top right corner of the passport
A passport does not constitute eligibility for citizenship in Britain. You must apply for a visa and apply for citizenship.
