Hello
My dad is a French Citizen (resides in the US on a Green Card for almost 48 years.. married a US Citizen). When I was born he registered me with the appropriate French governmental office as required. When I turned 18, he never went through and obtained a French passport for me.. the cost was an issue at that time..
18 years later.. I'd like to get my french passport..(keeping my American one as well).. What are the steps needed for this...?

It is hard to find out online what needs to be done.. Should he call the French consulate in NYC and inquire there? If someone has been through this specific process (french parent, registered birth etc) and can share the steps.. that would be great.. What I'm reading online seems to indicate in person interviews, in French, with governmental officials etc... and my French language skills are not up to this...
IF this is possible.. then I'd also like to take the needed steps to register MY children with the appropriate French office to convey french citizenship to them as well..

thanks!

 

Thanks..my mother is deceased...I'm not sure we have a passport for her. The link is helpful. Thank you

 

In case someone is searching about this topic and happens across this post, I thought I'd update.
The whole process was much easier than anticipated, since I was already registered in my father's family book. I was able to use the online form to obtain my French birth certificate with filiation from the Civil office in France. The copy was free and got here within a week of my request.
I then made an appointment with the French Consulate in NYC (it takes weeks to get an appointment.. however I was able to get a last minute cancellation appointment
Taking my French birth certificate, my US passport, my marriage license (as my last name had changed), 2 passport photos, and a copy of my most recent tax bill. I was able to obtain my ID Card
Interestingly, I could have just applied for my French Passport.. an ID card is not needed before one does that.. however.. I did not realize this until the appointment was almost done.. and by then I could not switch from an ID card application to a Passport application.
