Applying with multiple family members

I was told that if you are applying with relatives such as brothers and sisters that you just need to include their birth certificates with all of the other documents you are going to be sending in. I was also told I should include a hand written letter. So as I am applying with my brother we will have all the documents needed that show our proof of ancestry together in an envelope along with our birth certificates as well and then I will write out that my brother and I are both applying so that they will know that we are in need of 2 of the certificates of ancestry. After everything has been processed, 2 certificates of ancestry will be mailed back to us together in the same envelope.

The family research is indeed quite interesting. I have scanned every one of my documents into a folder to keep on my laptop. as for the things I needed from Europe I only had to get in contact with 2 people. My great Grandfather was actually born in France, So I had to get in touch with the city of Florange for His birth Certificate. Luckily everyone after that stayed fairly close to Dudelange, Luxembourg so I only had to contact the commune in Dudelange. What I liked about the Commune in Dudelange is the worker who actually responded to my emails and sent me the documents I needed was extremely nice. She sent me everything I needed asap and I actually received here in the U.S. in 6 days. She had also sent me duplicates of everything. All Certified. So I have everything needed to send in to Luxembourg and I also have extra certified copies that I can keep and do something special with like what you are talking about. As for organizing everything that is going to be sent in, that is just a nightmare for me. I happen to be super OCD when it comes to organizing.

I applied for myself, my sister, my father and my son. It was cheaper this way and it ended up ok. After we received the certificat de nationalite, my uncle applied for himself, his three kids and 6 grandchildren, 10 altogether. He sent the papers in January and in Frebruary he received the email saying he had to deposit 100 euros (10 for each certificat). So, no problems whatsovever.

The certificat de nationalite costs 10 euros.

Why is that? Would be way cheaper without having to travel to Lux for the phase 2 requirements.

Well, my process was made through the consulate of Luxembourg in Sao Paulo, which I learned never to use again. They made me pay about 700 euros for nothing. Well, but I submitted the papers for them on Feb 24th, 2014. They actually sent the papers to the Ministry of Justice in Luxembourg in the beginning of June,2014. On September 10th, 2014 I received the email saying that I was already a Luxembourgish citizen and just had to pay to receive the certificat the nationalité. After this, my uncles and cousins sent their documentation attached with my father's certificat de nationalité straight to the ministry and their process took two or three months. Those cousins who descend from a woman, my aunts, didnt get the certificate straight.. they received at home a plain white paper that stated they had a Luxembourgish ancestor... so now they have to go to Luxembourg for phase two.
