Hi all
Situation is the following:
DH and I come from an EU country and live in England.
DH and DS have double citizenship, I'll have my ceremony in one month.
I am going to travel tomorrow to our country for holidays, with DS and visiting DF. DH stuck here with work another couple of days. DS has DH's surname but both parents' name are on both DS's passport. What else do we need? Should DH sign a letter and should it be validated (police, etc?). I can show marriage certificate and DS's birth certificate but now I'm panicking. Thanks!
